Middlesbrough's January transfer window really kicked into gear last week as they secured three new signings. And there could be more in the final week of the window - though a lot could depend on the uncertain future of Emmanuel Latte Lath.

Ryan Giles became the first signing of the winter window, joining on loan from Hull City, 18 months after his initial year-long stay at the Riverside came to an end. He was soon followed by the permanent captures of Morgan Whittaker and George Edmundson after a busy week that also saw Boro secure the services of young non-league hotshot Brayden Johnson from Eastbourne Borough.

The moves come after Boro had previously sold Isaiah Jones to Luton Town. They've also found loan moves for Micah Hamilton, Sammy Silvera, George Gitau and Zach Hemming, while Matthew Hoppe's disappointing time at the club came to an end via a mutual termination of his contract. With one week remaining though, there's still plenty of potential ins and outs at Boro. Here's the current state of play.

A new priority

Middlesbrough were already exploring the possibility of strengthening their goalkeeper department this month and were competing with Watford over a loan deal for Bournemouth and Ireland keeper Mark Travers. In turn, it seemed likely that Seny Dieng would depart the club if they got that one over the line.

With Sol Brynn out long-term after dislocating his shoulder, the need for a goalkeeper ramped up at the end of last week when Dieng underwent Achilles surgery and will also now be out long-term, leaving Tom Glover as Boro's only senior keeper.

The big question is whether the keeper they get is Travers or someone else. Travers appeared close to joining Boro only for an injury to third-choice keeper Will Dennis to delay that. Travers has subsequently been on the bench for the Cherries' last two games. At this stage, it's uncertain whether Bournemouth can now let Travers go or not, with Boro believed to have alternative targets should they need to look elsewhere.

Emmanuel Latte Lath latest

The Emmanuel Latte Lath will-he-won't-he saga stretches into the final week of the window and now has an added complication. Under a serious transfer offer from MLS side Atlanta United, Latte Lath continued to play for Boro while the situation remained unresolved.

However, shortly into Saturday's defeat to Preston North End, Latte Lath pulled up with a groin injury and had to be withdrawn. As Boro await the results of a scan to reveal the severity of the issue, it's an added complication to uncertainty surrounding his future, which Boro have to resolve one way or the other this week.

Whether the injury completely ends the move to Atlanta or not will ultimately depend on the player and the MLS club. The lack of movement to this point suggests there is reluctance from the Boro striker to make the move Stateside, with hope that their offer would prompt Premier League bids not coming to fruition at this stage.

Though the MLS transfer window doesn't actually open until Friday, there was nothing stopping Latte Lath moving before that point if all was agreed. A transfer window is merely a registration window, and he could have joined at any point, with the MLS season not starting until next month and therefore registration not being an issue.

With Boro hosting Sunderland on Deadline Day for British clubs, they will ideally want the issue resolved before then, and will surely not contemplate a sale after the British deadline, at which point they won't be able to sign a replacement.

That will be the plan if Latte Lath does leave. Boro came into the window expecting Latte Lath to attract plenty of interest and prepared accordingly. Over the weekend, they were credited with interest in Slovakian international striker David Strelec who currently plays for Slovan Bratislava.

He is understood to be a player of interest to Boro, and is said to be keen on the move to Teesside. But the 23-year-old - who has ten goals this season, including two in the Champions League - is only one of a few players on Boro's shortlist of potential Latte Lath replacements, with Boro only needing to bring a striker in if the Ivorian does leave.

Other potential incomings

Middlesbrough have also made enquiries this month about strengthening their midfield, appreciating in the absence of Aidan Morris recently that they otherwise lack steel in their engine room. Former Rangers and Leeds United star Glen Kamara was a player they were looking closely at, though again, they were said to have alternative targets.

Kamara, currently ostracised at Stadde Rennais, would add steel and experience to Boro's side, while he proved last term at Leeds United that he has plenty of ability on the ball too. However, a high-earner in France after a summer move worth €10 million, the finances of a deal - likely to be a loan - are difficult and could require the potential Latte Lath money to complete.

Whether any of their alternative targets are more financially viable this month remains to be seen, particularly after spending £5m up front on Whittaker last week. As things stand, strengthening any other areas seems unlikely, unless there was an unexpected exit in the next week.

And possible exits

Lukas Engel is close to completing a loan move to MLS side FC Cincinnati following the arrival of Giles. That deal is expected to include an option to buy. Not for the want of trying, but the Dane has struggled to make an impact on Teesside.

With Edmundson in, Matt Clarke could leave before the end of the window too. The centre-back has fallen down the pecking order since Dael Fry and Rav van den Berg returned to fitness. Though a consistent performer in the last 12 month, he lacks the ability to play at the tempo Michael Carrick likes in possession. Derby County have been credited with interest in a loan move, with Carrick admitting his situation was one to be looked at this week.

So too is Alex Gilbert's. He's attracted interest from Swansea City this month and has struggled for game-time at Boro. Carrick has often talked him up and the role he could still play this season - particularly after his late winner at Hull City on New Year's Day. But Whittaker's arrival makes competition for places even harder in that area of the pitch.

Another means of potentially boosting revenue, Millwall are interested in making Josh Coburn's loan move a permanent one too, despite his injury-hit season to date. Though Boro are not actively looking to sell, they'd be willing to do business at the right price, with any money received going down in PSR calculations as pure profit for the academy graduate.

Any other business

Any other business is likely to be youth loans. Law McCabe could potentially go out if a new midfielder was brought in. George McCormick and Harley Hunt might benefit from playing regular first-team football elsewhere too - though a Clarke exit might mean Boro need to keep Hunt as a backup option.

Beyond that, any other business would be unexpected at this stage - but you can never say never in the final week of any transfer window. Anfernee Dijksteel is currently injured and has enjoyed an excellent season. But, out of contract at the end of the season, if they received a late bid and felt they could get an adequate replacement in time, you couldn't rule out them taking this final opportunity to sell for a fee.
