Manchester United boss David Moyes could be at risk of losing one of his young stars in the next transfer window.

Sources in Brazil claim 23-year-old Rafael has been considering his position in the squad and could be ready to return to his native country.

Corinthians are said to be keen on the right-back and see him as a perfect replacement for retiring star Alessandro.

Rafael currently has a healthy amount of competition at Old Trafford for a starting place with the likes of Chris Smalling Phil Jones and Johnny Evans able to play in his position.

United also signed Uruguayan right back Guillermo Varel in June.
