Wayne Rooney admits he's been unhappy with his form for Manchester United this season.

Given his first injury came in the opening match of the campaign against Reading, it is little wonder the 22-year-old views this year as a 'bit stop-start'.

Even before he got the second problem, in a freak training ground accident, when he was on a blistering run of nine goals in nine games for club and country, the Merseysider did not feel he was on top form.

"In terms of goalscoring, it was the best period of my career," he told Inside United.

"When you are on a run like that you go into every game believing you will get chances and that you will put them away.

"But overall, I don't actually think I was playing at my best."
