Manchester United and Manchester City are keeping tabs on FC Zurich teen Dimitri Mfomo.

The Switzerland youth international has attracted a bid of €600,000 from Udinese, says TMW, though Zurich refuse to do business for anything less than €1 million.

Mfomo won't turn 16 until May, when he can move between European countries.

United and City have been following the striker for the past 12 months and Udinese's interest may force their hand ahead of the summer market.
