Erik ten Hag's side had a united desire to beat Southampton after Casemiro's red card on Sunday afternoon - something that would have been unthinkable last season.
Manchester United were held to a goalless draw after Casemiro was shown his marching orders during the first half, but the reaction of Ten Hag's players suggest they wanted more.
That is far cry from last term, when rumours of a dressing room split between the Portuguese speakers - such as Cristiano Ronaldo and Bruno Fernandes - and the non-Portuguese speakers dominated the back pages. United players have since dispelled these reports - but that did not stop them from causing chaos under Ralf Rangnick.
