Manchester City have made an offer for Manchester United target Dayot Upamecano, according to reports.
United had previously agreed a fee for the 16-year-old defender, but the Daily Mail claims that City are now favourites for his signature.
The player, who plays for French club Valenciennes, is thought to be available for around £250,000.
He was part of the France Under-17 squad that won the European Championships in May.
