Arsenal boss Arsene Wenger admits the goal scoring form of Emmanuel Adebayor is concerning him.

Adebayor, 24, banged in 30 goals last season.

But the Togo striker is on 11 this term and nowhere near his sensational best as the Gunners head for Hull today.

Wenger said: "Adebayor has not had the same form. He dropped off a little bit but it happens.

"Cristiano Ronaldo at Manchester United scored 44 goals last year - it doesn't look like he'll get 44 this year.

"But I know Adebayor is working very hard to come back."
