The growing rumours that Jose Mourinho will be the next manager of Manchester United were further fuelled by a throw-away remark from Inter Milan dignitary Bedy Moratti on Saturday. The Portuguese's name has been increasingly linked by the media with the job amid the struggles of incumbent Louis van Gaal to win over the United faithful.

After Mourinho had visited former employer Massimo Moratti and his family for lunch, Bedy, filmed in a video interview with Calcio Mercato, said: "It was pleasant. He's still fantastic. He's been missed on a human level.
