Main problem with Chelsea at the minute IMO is they're not trying to build a team around just one player, they're trying to accomodate 3-4 at once and it simply can't work.
They're trying to play to Torres, Mata and Sturridge' strengths instead of focusing on one player. It really hampers them.
If I was in AVBs position then I'd try and build it around Mata, with Torres and Sturridge upfront.
Ivanovic Cahill Terry Cole
Ramires Mata Malouda
With Torres being the further forward of the two, have Ramires coming inside and Sturridge dropping to the right when needed to turn it to a 4-1-4-1, Torres staying up top on his own and then have Mata dictating the play from a slightly deeper role than he plays.
They definately need to bring in 3 new defenders though, Cole, Terry and Ivanovic are on a downward slide now.
