Manchester United face stiff competition for Real Mallorca prospect Toni Quetglas.
United were regarded as favourites for the 16 year-old striker ahead of Chelsea.
However, AS says Ajax are also in contact and have made an offer.
United also have tabled a proposal as Mallorca struggle to convince him to commit to pro terms.
Quetglas can leave Mallorca for a cut-price training fee this summer.
