Jose Mourinho has and never will be a normal football manager.

Remember his antics at Old Trafford in 2004 when, as Porto’s manager, he sprinted down the touchline to celebrate Costinha’s late equaliser that knocked Manchester United out of the Champions League.

Last year, Mourinho was sent to the stands after confronting referee Mark Clattenburg in United’s 0-0 draw against Burnley.

Howard Webb described the Portuguese’s behaviour as “crazy” in his Times column.

“Mourinho brings a lot of interest and colour to the league, and I was sad when he was sacked by Chelsea, but he will try to get any advantage he can from a referee,” the former Premier League official wrote. “The key is to be strong and to not let it affect you.

“It was crazy behaviour from Mourinho to get sent off. He is charged with one of the biggest clubs in the world and yet instead of concentrating on his own job at half-time, he has said something that is clearly serious enough for Mark to send him to the stands. Mark would not have acted unless it was serious.”

Mourinho's had many controversial moments

We’ve been used to it for 13 years now, since Mourinho landed on English soil to manage Chelsea in 2004.

The polarising figure has clashed with Arsene Wenger, gouged the eye of the late Tito Vilanova during a brawl in El Clasico and was fined for allegedly telling his Real Madrid players to purposely get booked in a Champions League match.

Pretty crazy, huh?

Damien Duff reflects on Barca CL tie

He must be an interesting man to work under. Damien Duff is many who has lived the Jose Mourinho experience, playing for the 54-year-old at Chelsea.

And Chelsea players were left somewhat bemused when Mourinho told them that he wanted to draw Barcelona in the 2004-05 Champions League.

It was a memorable encounter. The Blues recovered from a 2-1 first leg deficit to beat Barca 4-2 in the return fixture at Stamford Bridge and book their place in the quarter-final.

So perhaps Jose was right to want to want the Spanish giants.

'We thought it was crazy'

“We just steamrolled them – that was Mourinho being prepared,” Duff told FourFourTwo when asked about Chelsea’s fast start in the second leg.

“He’d told us that he wanted to draw Barcelona. We all thought that was crazy, as they had Ronaldinho and [Samuel] Eto’o, but he was right as usual!

“It was nice to score a goal, but then Ronaldinho showed us all up with his amazing performance.”
