The Spain international netted 27 times in La Liga last season - can he match that haul in the Premier League and help the Blues towards a first title since the 2009-10 season?POLL
With Chelsea having finally agreed a deal with Atletico Madrid for Diego Costa, attention can now turn to what the Brazil-born attacker can offer the Blues next season.
Costa joins Cesc Fabgregas in swapping Spain for west London after the Stamford Bridge outfit agreed to meet the buy-out clause in his contract.
The Spain international scored an incredible 27 league goals last season as Atleti claimed an unlikely La Liga title win, and he also netted eight times en route to the Champions League final.
Meanwhile, Chelsea’s horde of much-maligned strikers – Samuel Eto’o, Fernando Torres and Demba Ba – only managed 19 league goals between them.
Have the Blues finally got the talismanic forward they need to claim Premier League, and even European, glory next term? And how many goals can the 25-year-old be expected to net in his maiden campaign?
How much of an impact with Diego Costa have next season and how many goals will he score? Can he equal or even better Didier Drogba's title-winning haul of 29 goals in 2009-10?
