It's not going to plan for Tottenham Hotspur at the moment - that much is clear.

Ange Postecoglou's side sit 15th in the Premier League table, closer in points to the relegation zone than the top half. Four defeats in a row, with a home defeat against Leicester the latest in a string of disappointments.

Things are not going to get any easier, either. Spurs' injury issues are well-publicised: the spine of the team has been all-but ripped out with Guglielmo Vicario, Cristian Romero and Micky van de Ven long-term absentees; Dominic Solanke is out for another five weeks at least, while the returning Richarlison managed to get a goal but could only last 10 minutes into the second half against the Foxes.

Elsewhere, Pape Matar Sarr was not really fit enough to play against Leicester, but he did so anyway, while James Maddison missed out on the squad entirely - but isn't expected to be a long-term concern.

Postecoglou was asked about incoming transfers in the January window yet again after the defeat, and maintained his position that the squad needs help, with goalkeeper Antonin Kinsky the only arrival so far this month.

football.london understands that Spurs will attempt to add at least one more player to the club this week. But what area most requires reinforcement? And who should the club be targeting? Our writers give their verdict below...

Tottenham need help at the back, but Cristian Romero and Micky van de Ven are closing in on returns to the team. Tottenham need help up front, but Richarlison has made his long-awaited return to the team.

The cynical part of me thinks this was the plan all along. Try to make signings, but see players returning by the end of the transfer window as a reason not to have to make any - bar Antonin Kinsky of course.

If Spurs are only making one more signing, and good lord that's a shocking state of affairs for a team that has desperately needed reinforcements for months, then it should probably come in defence. That's where the biggest problems have been.

Remember under Antonio Conte when Spurs were heavily linked with a move for Alessandro Bastoni? Oh how we would love to have the 25-year-old now.

Inter are second in the Serie A table, three points behind Napoli with a game in hand and have kept eight clean sheets in their last 12 league games, with Bastoni playing a huge part in that. Signing him is a pipe dream now, but he would be my choice should only one deal get done.

I think it's fair to say that while the first XI is strong, Spurs' depth has been an issue across the field. They've addressed that in goal with the signing of Antonin Kinsky this month, and other areas could do with a boost.

A lot has been invested in attack in the not-too-distant past; Dominic Solanke, Brennan Johnson, Dejan Kulusevski and Wilson Odobert have all arrived on decent sums in the last two years, but that has been coupled with the departure of one of the club's all-time greats in Harry Kane. And Kulusevski this season has been deployed more as a midfielder, to great effect.

I think while injuries have hit hard, central midfield is probably the area in which additions are least urgent. Instead, it has to be another defender, whether that be a centre-back or full-back - or preferably someone who can play in either position.

Archie Gray has been the saving grace for Spurs in defence, and even then it's a lot to ask of an 18-year-old playing out of position. A new defender who can offer versatility to compete in the centre if either Cristian Romero or Micky van de Ven are out, or push Pedro Porro or Destiny Udogie for a starting place on the flanks is the biggest need, for me.

Tottenham needed players through the door when the January transfer window opened and nearly four weeks on that remains the case. I feel for Ange Postecoglou and his squad somewhat as they have had to endure the gruelling December and January schedule with virtually the same pool of players - everyone is shattered.

A centre-back and striker would be my priority. Spurs needed a centre-back weeks ago due to injuries picked up by Cristian Romero and Micky van de Ven so I think anyone will do at this point, with the pair nearing a return. Yarek Gasiorowski, a 20-year-old who has established himself in the Valencia first team this season, could be an option, while I also like Barcelona defender Andreas Christensen, who has recently returned from injury which has kept him out the whole season.

Up top and a short term loan deal could work here. Evan Ferguson could be suitable as he would offer Tottenham some sort of Premier League experience. The 20-year-old has an eye for goal and will offer competition to Dominic Solanke when he returns and the injury-prone Richarlison.

Centre-back and attack are the two areas Tottenham need to strengthen over the next week, ideally ahead of Sunday's vital Premier League game against Brentford. The north London club should not be in this position heading into the final week of the transfer window, though, as it was clear in early December that new signings needed to be signed off come the start of January.

Although Cristian Romero and Micky van de Ven should be back on the pitch very soon, Spurs still require a centre-back as there is no guarantee Tottenham's defenders are going to get through the rest of the season with a clean bill of health. Archie Gray and Radu Dragusin are also desperate for a breather from the team after playing non-stop since early December.

In attack, a player who can operate as a striker and from the wing would be ideal. However, given Dominic Solanke's injury, an out-and-out striker may be the best option due to Richarlison's frustrating injury record.

Liam Delap would be a brilliant signing but I cannot see that happening as there is no way Ipswich Town will sell their star man as that could effectively seal their return back to the Championship. A move for Lille ace Jonathan David could be a shrewd piece of business given his record in front of goal and also because of the fact that Spurs could sign him for a cut-price fee due to his current contract status.
