Swansea City attacker Andre Ayew says he'll overcome his form dip.
Ayew admits he must find away to become a more potent threat in front of goal.
He said: "Once people get to know you they start to use different tactics to keep you quiet.
"So I need to work even harder because things are becoming more difficult for me and the team.
"That is the nature of the game and that is why you have to respect people like Lionel Messi and Ronaldo who always find ways to influence a game.
"When you start and you are winning and scoring, people mark you with a different eye and if you keep working the same way you will not be effective.
"So to be ambitious and to be a great player you have to have more to help the team and the manager, and I have to do more. I have not achieved anything yet.
"We know we are facing a difficult side in Liverpool next, who have a big squad.
"But we are going there to try and get something and we will go there with confidence and belief."
