The Glazershave stepped into Manchester United midfielder Paul Pogba’s transfer plans to Real Madrid.
Marca says United owners, the Glazer family, have informed agent Mino Raiola that Pogba is not for sale following reports that the French man is ready to force an exit by embarking on strike.
Pogba has been heavily linked with moves to former club Juventus and Spanish giants Real Madrid in recent weeks with the latter believed to be preparing a £130m offer the World Cup winner.
But the Italian has been told specifically by the Glazer family that Pogba is not for sale.
Joel and Avram Glazer, who also own NFL outfit Tampa Bay Buccanneers, consider the midfielder essential to United and have made their feelings known.
