Former Manchester United and Arsenal striker Robin van Persie admits he could retire at the end of this season.

The 34-year-old won the title with Manchester United and is now enjoying what appears to be a swansong with first club Feyenoord.

"There will come a moment where I have to be honest with myself -- like now," Van Persie told NOS.

"Today with the final, it turned out to be great for everyone, myself included, and I am very happy with that.

"But people don't see the other side, which is that for the last three weeks, I have been going to bed at 10 p.m. every evening and that I eat the right things at the right time.

"There is a lot that comes with being able to deliver today and sometimes that is a struggle. Sometimes the recovery takes a little longer than I want."
