It may only be a matter of months ago that Louis van Gaal was in charge of Manchester United but it’s an entirely different club under Jose Mourinho.
Not only has Mourinho completed the signings of Eric Bailly, Henrikh Mkhitaryan, Zlatan Ibrahimovic and Paul Pogba but the Portuguese boss has already put together a three-match winning streak - something that Louis Van Gaal rarely achieved during his two years at Old Trafford.
There is now a winning mentality within the squad, epitomised by the way they snatched a 1-0 win against Hull on Saturday evening with a 92nd-minute winner from Marcus Rashford.
But how has Mourinho transformed the attitude in the squad in such a short space of time?
Well, captain Wayne Rooney thinks he knows.
Former boss Van Gaal often named his team up to 48 hours in advance of matches, including informing those players that didn't feature in the 18-man squad.
It meant that those that were left out became demoralised and ruined any team spirit at the club.
But now, Rooney believes Mourinho’s method of delaying naming his squad is benefiting the club immensely.
“Everyone knows that if you work hard, then you will eventually have the opportunity to show your worth,” Rooney said, per Manchester Evening News.
“Last year many players knew that they would be starting on the bench even days before the game.
“Some would even know that they would not be travelling with the squad. This year we are more of a group and this is our true strength.”
United head into the international break with a 100% record, alongside title rivals Chelsea and Manchester City.
The club captain believes that Mourinho, whose fast starts with Chelsea have helped them win the league in previous seasons, thinks that nine points from their first three matches has given the players the confidence they needed.
“If we think of the years in which he won the title with Chelsea, Mourinho always made a good start,” added Rooney.
“This is good for us as a team, we feel more confident in our ability.
“Jose has brought his winning mentality into the dressing room and the players have grasped it, whereas this is something that we probably lacked in the last two years.”
