Tomas Rosicky admits it's crucial Arsenal hold onto captain Thierry Henry.

"Thierry is a big player for us. He is our captain and we need him," Rosicky told the Daily Star. "Of course it would be a blow if we lost him.

"I think we can challenge the top teams. We have shown that already by beating them.

"But we have had problems against the smaller teams. I think it is down to stuff we can work on."
