Football fans loved what Willian did when Jose Mourinho passed Matic a tactical note

Willian in action vs Man Utd..

Manchester United may have just pulled off their biggest win of their season so far.

The Red Devils gave their second-place aspirations a well-timed boost against top-four rivals Chelsea, coming from behind to win 2-1 at Old Trafford.

Willian had given the visitors a deserved first-half lead, but Romelu Lukaku and substitute Jesse Lingard scored to give Jose Mourinho three points which will taste sweeter than any other this season.

It was a big day for Nemanja Matic, with the Serbian midfielder taking on his former club for the second time after his £40m summer move and he turned in a very composed display.

In the midfield engine room, Matic done a fantastic job screening the defence and freeing up Paul Pogba, who was handed a start in his favoured role on the left of a midfield three.

And, the Serb was involved in quite a peculiar incident late in the second period with former teammate Willian.

Mourinho passed Eric Baily a tactical note to hand to his midfield maestro when he came on as a substitute and the Brazilian literally chased Matic down to try and get a sneak peek.

The United man certainly didn't look too impressed...

It was a pretty funny incident, however, it will never reach the levels of former Arsenal right-back Emmanuel Eboue trying to listen in on North Korea's tactics while playing for Ivory Coast
