Jose Mourinho was in charge for the latter campaign and, despite securing Europa League, EFL Cup and Community Shield glory, along with Champions League qualification, knows they have to do better in the league.
"You get the feeling that Chelsea didn't really want Matic to go, but players can push for a move at times and that is why this deal feels different compared to Petr Cech's move from Chelsea to Arsenal a couple of years back".
His final message to us that season was simple - enjoy your summer, bask in the glory, but be prepared to work when you get back, .
'For me Matic is a fantastic player - a real, real top player, ' he said.
All of a sudden United are in the driving seat ahead of Chelsea to win the Premier League.
"We had an opportunity to equalise, Marcus (Rashford) had a good chance and didn't score, unluckily for us, but this is football".
Matic believes the 24-year-old will have had his confidence boosted by his goal and expects him to hit the ground running when the Premier League begins this weekend.
"In every position, we have two very good players, so I am optimistic for this season and let's forget about Madrid".
"But now the Premier League, then the Champions League will come, the FA Cup and the League Cup".
"You are not only improving United in defensive midfield, you are making Pogba better, [Ander] Herrera better".
Chelsea's squad, or whatever's left of it by the time kick-off rolls around in a little over 48 hours, face a theoretically much weaker Burnley side at Stamford Bridge, but if there is one thing that Burnley won't do is make it easy for the boys in brand new Nike blue.
