London (AFP) - Wayne Rooney has insisted he has got a "lot of football left" amid suggestions his days as a regular starting player for Manchester United could be coming to a close.

United and England captain Rooney, who made his name as a goal-scoring forward, has been a substitute in five of the last six matches for club and country, including the Red Devils' goal-less draw away to arch-rivals Liverpool on Tuesday when he came on for Marcus Rashford.

And Rooney has no time for suggestions that he is now a 25-games-a-season player, insisting he wants to force his way back into the starting line-ups of both United manager Jose Mourinho and England interim boss Gareth Southgate.

"I'd like to think I can play every game, but obviously it's the manger's decision and I respect the decision," he said. "I'll be ready when needed.

"Not in my mind (do I think I've reached the point when I accept only getting 25 games a season). Maybe in other people's minds but not mine.

"I'm 31 next week. I've got a lot of football left."

Rooney's next chance to start for United will come in Thursday's Europa League match against Fenerbahce.
