Manchester United are back and so is the old Jose Mourinho.

The Portuguese often cut a forlorn figure on the touchline last term, despite guiding the Red Devils to the EFL Cup and Europa League in his first campaign in charge.

Now that his side are enjoying their best start to a season since 2011/12, the bolshy, quick-witted, and downright hilarious Mourinho seems to have re-emerged.

Admittedly, that side to his personality doesn't always manifest itself in the most positive way.

The former Chelsea boss has had countless run-ins with the FA over the years and he may find himself in hot water once again after United's 1-0 win against Southampton.

It was a stressful 90 minutes down at St Mary's despite them staying within touching distance of Manchester City at the top of the table thanks to another goal from Romelu Lukaku.

Mourinho even blamed the fact that it was too hot - in England, in September - for the fact they didn't win by more.

In the dying seconds, it all got too much for him and he was sent to the stands for his animated antics on the touchline.

In his defence, his behaviour wasn't anywhere near what Antonio Conte and Jurgen Klopp do every week, but he did encroach onto the pitch in his excitement.

Mourinho continued into the tunnel 

Fourth official Mike Jones took umbrage with the incident and dutifully reported it to referee Craig Pawson.

United will find out at some point today whether their manager will be punished, but his previous record could count against him as was twice sent off last season in games against Burnley and West Ham.

The Mirror also claim he went into the referee's room after the final whistle with another member of United's staff, though it's not known whether he was invited in. Some officials are happy to discuss matters after the game.

Mourinho had reportedly been complaining in the tunnel that he had no idea why he'd been dismissed.

The FA are waiting for Pawson's report before deciding what action, if any, they will take.

Should Mourinho be punished by the FA? Have your say in the comments.
