Transfer window: Premier League club-by-club guide

Arsenal
Money to spend Arsène Wenger still has a large transfer kitty. Ivan Gazidis, the chief executive, has confirmed this and, in short, Wenger can spend whatever he wants to strengthen the squad. The age-old question, though, concerns whether the manager can find sufficient value in the market or quality that represents an upgrade on what he already has.
What's needed A striker, particularly as Wenger will lose Gervinho to the Africa Cup of Nations; a left-back, as the club are open to offers for André Santos and maybe a defensive midfielder. Wojciech Szczesny is not entirely secure as the long-term answer in goal.
Who they're after Thierry Henry, on loan during the MLS off-season, Demba Ba, Wilfried Zaha and Luke Shaw are all prime targets. David Hytner
Aston Villa
Money to spend It is a case of needs must at Villa Park, which means Randy Lerner, the club's owner, will make funds available to help stave off the threat of relegation but there will be no repeat of the club-record deal that brought Darren Bent to the club two years ago. The transfer kitty is likely to be £10m at most, Kazinform has learnt from the Guardian.
What's needed Where do you start? Apart from goalkeeper and right-back, Villa need strengthening in just about every position. Experience is the key requirement, given the number of youngsters in Villa's team. A central defender, combative midfielder, striker and left-back have been targeted.
Who they're after Steve Morison, the Wales international striker who is out of favour at Norwich, Lambert's former club, is an option while loan moves for Manchester City's John Guidetti and Tottenham's Tom Huddlestone are possibilities. Stuart James
Chelsea
Money to spend Funding, as ever, is available and will be spent. The outlay may not be as lavish as two years ago, when Fernando Torres and David Luiz arrived for a combined £73.3m, but it will still be impressive.
What's needed A striker to back up Torres given Daniel Sturridge's sale to Liverpool, possibly a second striker to operate off the Spaniard, a central midfielder and, at a push, a left-back.
Who they're after The ideal remains Radamel Falcao but there is an acceptance Atlético Madrid will not sell in January, so Chelsea are monitoring Demba Ba, Bayer Leverkusen's Andre Schürrle, Barcelona's David Villa and the Borussia Dortmund pair Marco Reus and Robert Lewandowski. In midfield, Corinthians' Paulinho is a target with Everton likely to retain Marouane Fellaini until the summer. Southhampton's Luke Shaw and Everton's Leighton Baines have attracted interest at left-back. Dominic Fifield
