Marouane Fellaini let his emotions get the better of him on his return to Everton, as his rash decision ultimately cost Manchester United victory in the two teams' 1-1 draw.
That is the view of Match of the Day 2 pundits Jermaine Jenas and Troy Deeney, who also believe Mourinho's decision to bring the Belgian on was the right one as the United boss looked to protect his side's slender advantage.
Fellaini was introduced on 85 minutes in a bid to sure up the United defence against the expected aerial onslaught, but he instead gave away a penalty following a badly-timed lunge on Idrissa Gueye with stoppage time approaching.
