Marouane Fellaini did not have the best of days at Goodison Park on Sunday, but that did not stop the Manchester United midfielder sharing a glass of bubbly with his twin brother Mansour on Tuesday. The brothers were recently the subject of a mix-up involving Chelsea boss Jose Mourinho prior to the Blues' crunch clash with United at Stamford Bridge on April 18. Following his side's 1-0 victory over Louis van Gaal's side, Mourinho revealed he prepared his Chelsea players to deal with the threat of Fellaini all week – only to be told by a hotel doorman that the Belgian was not playing.

Following Manchester United's 3-0 loss against Everton, Fellaini spent Tuesday chilling out with his brother . Fellaini was substituted at half-time against the Toffees as Louis van Gaal's side struggled at Goodison Park . Mourinho planned for Kurt Zouma to man mark Fellaini - with teenager Ruben Loftus-Cheek playing the 6ft 4in midfielder in training. But he feared his tactical master plan was set to be for nothing when he was told that the United powerhouse was not playing by the doorman at the club's hotel. Mourinho, relaying his conversation with the doorman, said: 'Fellaini doesn't play because he was here to get tickets for the game from Eden Hazard. He was dressed in jeans, this and that'.

'(It) didn't smell well for me. I go to Google and I put 'Fellaini brother'. 'So I go with the pictures to the doorman. I say 'hey, this one or this one?' And he looks 'this one'.
