Chelsea didn't make many moves this past summer, but the January transfer period might be quite a different story as new manager Andre Villas-Boas may consider some major changes to strengthen the club's chances of winning a Premier League title.

The Blues go into Saturday's match with Swansea City with an impressive record of three wins, one draw, and one loss. Villas-Boas has proven to be an intense manager, who is demanding of his players.

Every manager has their own style, and Villas-Boas may quietly want to see some new faces at Stamford Bridge. Change may need to be in store if the Blues expect to compete with the impressive form of Manchester United. The Red Devils defeated Chelsea 3-1 at Old Trafford, and United will be quickly on their way to another Premier League title should they maintain their pace.

Gary Cahill, who had been strongly linked to Arsenal over the summer, might be a Chelsea target, according to Daily Mirror. Cahill, 25, is among the best centre backs in the Premier League, and struggling Bolton would likely be keen on moving him in January, and may need some leverage against Arsenal after some contentious verbal exchanges with Arsene Wenger.

Daily Mirror also reported that Chelsea are interested in adding Everton's Ross Barkley. The 17-year-old midfielder is valued at £20 million. Everton boss David Moyles doesn't want to part with Barkley, but there might be a bidding war between Chelsea and Manchester United, which means Bolton could have perhaps £18 million to reinvest in other areas.

Chelsea critics are quick to point out that the Blues have too many older players on the squad, so adding Cahill, and certainly Barkley, would make the club younger.

Another way Chelsea can get younger is by unloading some older players. According to Metro, midfield star Frank Lampard is the target of Anzhi Makhachkala. The wealthy Russian club have already added former Inter Milan striker Samuel Eto'o, and probably wouldn't mind overbidding for Lampard. The club is also interested in 31-year-old Liverpool star Steven Gerrard.

Metro also report that 19-year-old Neymar still has a chance to play for the Blues, after snubbing Real Madrid.Chelsea will also be competing with Manchester City among other big-name clubs.

There has been wide speculation that Neymar's agent has been spreading false rumours, so it's tough to gauge how interested clubs are in the young Brazilian.
