It has only taken two games and two poor results - one of which looked generally quite decent at the time - for real questions to be asked of Chelsea. The quality, or perhaps lack thereof, in the squad depth has been exposed, and a few minor Enzo Maresca issues have emerged.

It is nothing that cannot be solved. For Maresca, rotating his side a bit more during a busy period and then making more substitutes would constitute and allay a lot of the problems. The squad thing is a bit tougher.

Chelsea have a big group but Maresca's trust in them doesn't seem to extend outside of 14 or so names, naturally. Injuries in key positions have put a strain on even more influential starters and now, with January staring back in close proximity, the chance to amend and ease the burden is here.

Below, football.london looks at the current biggest stories heading into the window.

Kolo Muani contact

Chelsea are preparing to contact Paris Saint-Germain ahead of a possible move in the January transfer window. The out-of-favour forward has only started two league games for Luis Enrique this season.

Having made the move from Eintracht Frankfurt, where Kolo Muani excelled and made a name for himself, catching the eye of Chelsea at the time, it has been hard going back in France. He only scored six times in Ligue 1 last year despite costing over £80million.

However, according to Foot Mercato, Chelsea have identified the 26-year-old as a potential option for mid-season attacking reinforcement. Monaco, RB Leipzig, Manchester United, Juventus, Galatasaray, and Milan are all sniffing around too.

PSG are said to prefer a loan deal with an obligation to buy rather than a straight sale. The Parisiens have previously been linked with a host of Chelsea players including Christopher Nkunku.

football.london says: There is only a slight appeal to loaning Kolo Muani in January, and that is with the caveat that there is no obligation to buy. As a versatile forward he does have his merits but really, this isn't the sort of deal Chelsea need.

To help and support Nicolas Jackson they need to find an Olivier Giroud figure. Maybe the picture changes come the summer and maybe it involves Victor Osimhen or Viktor Gyokeres (or Liam Delap). For next month, it really shouldn't be Kolo Muani.

PSG want him out, his agent wants some interest, and Chelsea are an easy team to link. It would be a surprise if there were many legs to this at all. What is worth noting is the Nkunku point.

He is not happy with his game time, understandably, and PSG might be able to give him that and some extra spark. A swap deal would be extremely tough to arrange mid-season but maybe it is one to look at further down the line.

Loan decisions

Chelsea's bare midfield could leave them turning to two players they already own in a bid to add steel to the spine of the team. In January, both Andrey Santos and Lesley Ugochukwu could return.

Santos, currently away with BlueCo-owned RC Strasbourg, is having probably the best season of a top-flight loan player across the continent right now and is a world away from this time last year when he couldn't get on the pitch for Nottingham Forest. As for Ugochukwu, he's in Santos' position 12 months ago.

The Frenchman is getting more game time now and a change of management at St Mary's Stadium promises to offer him enough to come as well, but the chance of him coming back in some way is tantalising. Chelsea could simply shuffle the deck and shift Ugochukwu to the more-readily monitored and controlled environment of Strasbourg under Liam Rosenior, or they could actually add these two to the reserves for Maresca.

Carney Chukwuemeka and Cesare Casadei - two of the 'B-team', and in Chukwuemeka's case, sometimes not even that - are both likely to depart in some form. Kiernan Dewsbury-Hall might do as well. This would leave room for at least one of Santos or Ugochukwu.

football.london says: There is an immediate temptation to turn to Santos as genuine first-class quality at a time of need, especially if Romeo Lavia is going to continue being injured every few weeks. How does that balance with the risk of upending his brilliant time in France and taking him out of such a good personal moment?

Ugochukwu is the more straightforward case. He could really do with another club looking after him. Chelsea could definitely do with someone of his build and style. One of these two will surely have to have a role to play at Stamford Bridge, though, in the long and short of it all.
