The Ivory Coast ace is keen to make an impression again after Fernando Torres' British record move to Stamford Bridge.
He declared: "I have scored nine goals so far this season and my target is to pass the 12 I scored last season. It is what motivates me every game.
"I was pleased to score so soon after coming on at the weekend. It was a very important goal, which keeps us in the FA Cup.
"Now we have to get three points at Sunderland. With the situation at the top of the Premier League, we have to win every game."
