The January transfer window in the Premier League opened up on the 1st of January and runs till the end of the month, with a number of clubs in need of strengthening their squads as they go into the business end of the season.
Here, we take a look at that one area/player that the top six clubs in England need to focus on during this month.
1. Manchester City
Manchester City selling Ferran Torres to Barcelona might in all probability be the only piece of transfer business they will conduct in January and while they still need to sign a new number 9, that issue might only be revisited in the summer.
Pep Guardiola has arguably the best side in the league and a glance at their form shows that they currently are doing extremely well with a striker and that they will keep their £100million budget until the summer.
A host of top names continued to be linked to Liverpool, but Jurgen Klopp has shown in the past that he is reluctant to buy in January unless it is a player of the ilk of Virgil van Dijk.
The Reds star players in Mohamed Salah and Sadio Mane will be missing due to the Africa Cup of Nations, but considering that they might only miss two matches - the club might just not shop in the window.
However, if they are to strengthen one area, then that is in attack, especially in the absence of their top players.
Thomas Tuchel needs a proper replacement for Ben Chilwell at left-back, considering that England international might miss the rest of the season due to injury.
Lucas Digne from Everton has been heavily linked with Chelsea as he is not in the plans under Rafael Benitez, while Theo Hernandez from AC Milan is another name being bandied about - but he might just be too expensive for them to sign this window.
Arsenal spent big last summer, but Mikel Arteta needs to address the lack of depth in midfield, look for a right-sided forward considering that Nicolas Pepe's future looks uncertain and also shop for a striker with Pierre-Emerick Aubameyang being frozen out and looking like he is on the way out of the club.
The Spaniard is not expected to have a lot of money to spend in January and it will be interesting to see what he decides to do this month.
5. Tottenham Hotspur
Antonio Conte is in the market for a centre-half and a player on the right-flank, but nothing is certain considering Daniel Levy is not particularly known for spending big on players.
However, the likes of Dele Alli, Harry Winks, Joe Rodon and Steven Bergwijn are all said to be on the way out and how much the club could spend, depends on whether they can sell even two of the above players.
6. Manchester United
Ralf Rangnick needs to buy a defensive midfielder immediately and Declan Rice is understood to be Manchester United's number one target - though there is no clarity whether the player would want to move to Old Trafford or whether West Ham United would let him leave.
The club also needs to sign a centre-back and get a replacement for Anthony Martial, who is set to leave the club.
