Kicking off this list is recently anointed Spain international Diego Costa, who made a rather controversial debut for La Roja earlier this month after a lengthy legal spat with the Brazilian national team.
The 25 year-old has been in sensational form at club level this season to find 30 goals in 40 appearances for Atletico Madrid, whilst a 22 goal-haul in La Liga has left Costa as the division’s second top scorer.
The prolific return comes off the back of a sensational run in last term’s Copa del Rey, in which the Brazilian-born forward netted eight times in eight outings as Diego Simeone’s side went on to claim the Spanish accolade.
Measuring in at 6 foot 2 and famed for his surging runs at opposition defences, the former Braga man’s physical menace is perfect for Chelsea’s lonesome striker role. Furthermore, Alteti’s disciplined style can be directly compared with the Blues’ ethos under Jose Mourinho, suggesting Costa would quickly acclimatise to the brand of football in West London.
After extending his contract earlier in the season, the 6 foot 2 forward now comes with a release clause of £32million. That’s certainly within Chelsea’s financial reach, but Costa’s impeccable form this term has generated interest throughout the continent.
Some have speculated that the Stamford Bridge side could have the inside track on the South American powerhouse, if they’re willing to let Atletico loan sensation and current No.1 Thibaut Courtois move the other way on a permanent basis.
