He's yet to get off the mark this season but Clarke won't single him out for that either.
Clarke said: "It's a squad game and players have to be ready when selected. I have to pick the best 11 I can. When you're a star - and Nicolas is - he will grab the headlines.
"But football's a team game. It's everybody's job to create and score goals, not just Nic's. His form, by and large, has been good. He has brought a different dimension to the team.
"We need to find more creativity going forward, but that does not apply just to Nicolas.
"It's up to everyone in the team to step up to the mark, to create more and score one."
