Real Sociedad fear losing young star Mikel Oyarzabal to Manchester City.

AS says City have identified Oyarzabal as a potential replacement for Bayern Munich target Leroy Sane.

They have already contacted the player's camp and assured him they'd be prepared to pay his €75m buyout clause should La Real refuse to do business.

It would be a massive blow for Real Sociedad should they lose the Spain U21 star, having just handed him the No10 shirt.

There is real fear inside La Real that City will make a formal move in the coming days.
