costa, torres, drogba, chelsea will be fine. they used shurrle in a false 9 last season as well. no one is willing to pay torres wages and roman doesn't want to take a 10m loss on him, so he will stay. atletico is the only ones interested in him and they don't have a lot of money.
rom will be sold, especially since chelsea is committed to FFP (which i applaud). Wolfsburg can offer champions league, so can Liverpool. I don't see him going to Liverpool though cause Mou sees them as a direct threat, we are less of a threat in his mind i gather. I don't see him going to spurs because who would want to? chaotic, new manager every half season, and they have addebayor, soldado and harry kane. So really for me it's Wolfsburg with his bud De Bruyne or Everton with whom he played last season.
