Manchester United manager Jose Mourinho said his side ought to have been "smoking cigars" after they made hard work of an eventual 4-2 win away to Watford on Tuesday. But the Portuguese boss said his side had "lost stability" when midfielder Nemanja Matic went off early in the second half with a "muscular" injury. United were 3-0 up before half-time at a freezing Vicarage Road thanks to Ashley Young's double and a goal from Anthony Martial. But after the break the Hornets struck twice through substitute Troy Deeney's penalty and Abdoulaye Doucoure before United's Jesse Lingard finally put the result beyond doubt four minutes from time.
