The £32 million signing got his Chelsea career off to the perfect start on Sunday, scoring a goal as the Blues came back from a goal down to record a 2-1 win over the Slovenian team Olimpija Ljubljana.
The hosts took the lead through Nik Kapun in the 40th minute but Diego Costa levelled matters ten minutes into the second half.
The 25-year-old ran on to a through-ball from his fellow Spain international and summer recruit Cesc Fábregas and took a touch between the two centre-backs before rifling an unstoppable shot beyond the helpless goalkeeper.
Kurt Zouma poked in the winner eight minutes later when he followed up Fernando Torres’ parried shot.
