“The manager wants us to be focused every game, winning every game. Before the game he was shouting before ‘come on guys, we have to finish properly, winning mentality’.
“So, yeah, we showed it again. 1-0 down, suffering a bit, but then we create chances and could have scored even more than two.
“But, like I say, a big way to finish the season with a victory and (it) gives a bit of enjoyment to the fans.”
The result saw United equal the club’s record of 27 home wins in all competitions in a single campaign, while also meaning they finished 17 points better off than last season.
“100 per cent, for sure, the improvement is there,” De Gea told MUTV. “Of course we still have a gap to improve but, yeah, a massive improvement from last season.
“Winning a cup, finish third – it’s never easy to finish in the Champions League places in England.
“And then we have another final, a big final, so I think at the moment it is a great year.”
As for Fulham, the defeat at Old Trafford was frustrating but this was a season to cherish having finished 10th on their return to the top-flight.
