Manchester United are being offered some of Europe's biggest names this summer.
However, United directors are wary of being used as a stalking horse for other deals , says the Daily Mail.
Real Madrid are asking if they have interest in Angel di Maria with agent Jorge Mendes ready to move the Argentine winger to make way for his other client James Rodriguez from Monaco.
Di Maria has also been discussed in Madrid's talks involving Radamel Falcao from Monaco.
Carlo Ancelotti would prefer Di Maria to stay and he is a popular figure in the dressing room.
