LONDON - CRISTIANO Ronaldo believes he could be back playing for Manchester United by the end of September after completing his recovery from ankle surgery.

The Portuguese winger went under the knife in July following the Euro 2008 tournmament and initial forecasts were that he could be out of action until late October and possibly November.

But Ronaldo, who scored 42 goals last season to fire United to the Premier League title and Champions League, has been told his rehabilitation is ahead of schedule and he is on track for an early return to action.

'I am more than happy with my progress and I hope to be back playing for United by the end of September - that is my target and it is a realistic one.

'It has been frustrating to miss the start of the Premier League season but I am pleased with my rehabilitation and, hopefully, I'll be ready soon.'
