The draw restored some kind of pride for Mourinho following the 5-0 humiliation of earlier that year, but there was more to come...
7. Barcelona 0 Real Madrid 1 - April 20, 2011
MOURINHO finally got his first win over Pep as Real boss - and in the Copa del Rey final, no less.
It took extra time, but a Ronaldo header proved decisive as Jose delved into his bag of tactical tricks to orchestrate the win.
He played Ronaldo up front - a novelty five years ago - and Pepe in midfield in a bid to stifle Messi and Co's creativity... To great effect.
After Pep complained about a Pedro goal being ruled out for offside, Mourinho antagonised the Spaniard, saying: "Up until now there was a very small group of coaches who didn't talk about referees and a larger group who did.
"Now, with Pep's comments, we have started a new era with a third group, featuring only one person, a man who criticises [the referee] when he makes good decisions.
"This is completely new to me."
Pep retaliated brutally, snapping: "As senor Mourinho has called me Pep, I'm going to call him Jose.
"Tomorrow we will face each other on the pitch. Off the pitch he's won. He's been winning off the pitch all season.
"Let them give him a Champions League for it so he can enjoy it and take it home.
"In the press room he is 'el p*** jefe' (the f***ing boss) and the one who knows more than everyone else."

After the tie, Jose fumed: "One day, I would like Josep Guardiola to win this competition properly.
"Josep Guardiola is a fantastic coach. But I have won two Champions Leagues and he has won [only] one Champions League - and that is one that would embarrass me.
"I would be ashamed to have won it with the scandal of Stamford Bridge. If he wins it this year, it will be with the scandal of the Bernabeu.
"Deep down, if they are good people, it cannot taste right for them.
"I hope one day Guardiola has the chance of winning a brilliant, clean championship with no scandal."

But Messi struck late to gift Guardiola another title - and another win over now fierce rival Mourinho.
Any hopes of relieved tension were ill-judged however, as the second leg at the Nou Camp played host to some horrific scenes, including Jose poking Barca assistant Tito Vilanova in the eye after a shocking tackle from Marcelo on Cesc Fabregas.
Jose then gestured towards Messi and Dani Alves before venting his frustration on the Barca ball-boys.
After the game, Barca defender Pique slammed Mourinho, saying: "Someone has to take action on the matter. Mourinho is destroying Spanish football."
Jose meanwhile defended his actions, adding: "We intended to play like men and not fall on the ground at the slightest touch. I have been taught to play like a man and not to fall first."

The game was Barca's first home loss in 55 matches, Real's first Clasico win in four years and their first at the Nou Camp in five years.
After the game, Guardiola quipped: "We can't expect to always be up to the standard but it's a pity we faltered in the decisive moment.
As Real romped home to the league title, Guardiola said he needed some time off.
Mourinho - ever the gentlemen - paid him an emotionless send-off, saying: "It's his life, but for me it's unthinkable to take a sabbatical.
"He is younger than me, but I'm not tired."

The game ended 2-2 after extra-time, with Pep's side coming out on top on penalties after the Blues were reduced to ten-men thanks to a horror tackle from Ramires on Mario Gotze.
Despite losing once again to his ferocious rival, Mourinho bitterly claimed: "The best team clearly lost. They just scored one more penalty."

OVERALL SCORE: Pep 7, Jose 3, Draw 6
