Man United entered the Christmas period with just two Premier League wins between September and December.
However, Mourinho’s men have won every single game in reaction to their ignominious 1-1 draw with Everton in early December, and can go to within two points of second placed Liverpool with a win over Jurgen Klopp’s men on Sunday.
Mata, writing in his weekly blog, was quick to shed light on the buoyant atmosphere in the dressing room following such an excellent run of form.
“Now it’s time to keep pushing to make this season a great one,” he said.
“Personally, the festive season has left me very happy, because I love to have my family at home with me, but also thanks to our wins against West Ham and Reading, a reflection of the team’s good moment.
“In London we were able to take our chances to beat a good side, and in the FA Cup we showed that this is a competition we really care about. This Monday we will know the name of our next rival.
“I want to congratulate Wayne Rooney once again for equaling Sir Bobby Charlton’s 249 goals with United. He deserves an applause from the football world, as the legend he is, for his amazing achievement.
“We are also focused on the EFL Cup and we play this Tuesday at home against Hull City. Although they are at the bottom of the Premier League table, they’ve just won against Swansea in the FA Cup and I’m sure they will come to Old Trafford with an extra motivation to try to beat us.”
Remember when United went ten successive home games without scoring a first-half goal? That was less than a year ago. Mourinho has monumentally galvanised a previously confidence-sapped, generally unhappy group of players in the space of a few months.
He has already eclipsed Louis van Gaal when it comes to the number of times his side has scored four or more goals in a game, encouraging a style capable of exciting supporters as well as yielding results.
But perhaps the most important change witnessed under Mourinho, above anything, is that these players are now enjoying life at Old Trafford once again.
