Argentina's Banfield are waiting for Manchester United to make an offer for midfielder Nicolas Bertolo.

The 23-year-old, valued at around £4million, has caught the eye of scouts and United are expected to be represented at Banfield's game at Colon tonight.

< Banfield's sporting director Hector Clide has declared that he is expecting an approach from United.

"I am aware of the subject and it is not unusual because the kid has had a good year," Clide told TyC Sports.

"We expect news about this subject."

Bertolo is half owned by Banfield, while former club Boca Juniors also hold a 50 per cent share of the player.
