Arsenal boss Arsene Wenger has urged fans to keep the faith.

. Wenger insists he knows what he's doing after selling Robin van Persie to Manchester United.

He said: "I'm having the same questions now with Robin van Persie as I did when Thierry Henry left.

"Last season I had to answer, "Why do you play Van Persie as a centre forward?" And you don't have to convince me that we have lost an exceptional player. I was the first to say that.

"We have to get around that by sharing more of the goals than we did before with Van Persie. If Giroud scores 20 and Podolski scores 20, we will get goals. I'm convinced about that.

"We have to share them around. But, a month ago, they did not know each other. The understanding is missing, but it will come."
