I think the idea that you can move on whenever you like might get tested this January. Sitting as we do in amongst clubs chasing European qualification, selling Caicedo or Trossard to one of those competitors mid season is not something I think TB would be keen on.
Chelsea were not scouting globally for about 7 recent recruits, they have been one stop shopping at BHAFC. It's paper talk at the moment, but Caicedo, Trossard, and Sanchez have all been linked with a move to Chelsea in recent days as well.
