1. Diego Costa (Atletico Madrid)

According to Mirror, Athletico Madrid striker Diego Costa is a target for Chelsea with an eye for a possible summer transfer. Jose Mourinho has hinted that he may not make any striking additions in January, and while that may be unlikely, if it meant that it would result in the summer arrival of Costa, it would certainly make sense.

While Costa himself would be unlikely to be open to a move six months ahead of the World Cup, there is the possibility of a deal being done in advance to bring him to Stamford Bridge in the summer. Costa has just obtained Spanish citizenship, and will be keen to impress Spanish national team coach Vicente Del Bosque, having already netted 19 goals in 19 league appearances along with 4 goals in 3 appearances in the Champions League.

Chelsea will have the inside track given the fact that Costa’s agent Jorge Mendes is also the agent of Jose Mourinho.
