Costa nets debut goal as Chelsea come back to win
After the hosts had taken the lead through Nik Kapun’s 40th-minute strike, striker Costa levelled the match 10 minutes into the second half, converting a through-ball from his fellow Spain international and summer recruit Cesc Fabregas, who was also making his bow for his new club.
Eight minutes later, defender Kurt Zouma prodded in the winner, following-up a Fernando Torres shot that had been parried.
