"I admit it, Messi made me feel embarrassed at the Wembley final"

Pep Guardiola's work at Barcelona reached its peak in 2011. That year, Barça played an almost heavenly football and won LaLiga and the Champions League.

In the final of the European competition, the Catalans gave an outstanding performance against Manchester United in their own country and in a mythical stadium like Wembley. But it seemed that they would have won regardless of the team that had been put in front of them.

That night was also one of the biggest of Leo Messi's career. And one of the darkest in the history of Sir Alex Ferguson's Manchester United.

Rio Ferdinand spoke about it in 'Copa90'. "Messi had so much confidence. That Barça gave us a lesson at Wembley," said Ferdinand, who also recalled the match that brought Cristiano Ronaldo to Manchester United.

The former United centre-half went into detail: "I was there, watching them lift the trophy, and Giggs, Scholes and I were together, with our hands on our mouths, and I said: 'I'm ashamed."

The former England international also had words of praise for Ronaldinho, although he soon established a difference with Leo: "Messi was a real killer. Ronaldinho was a magician, but Messi did all that and also always ended up marking or giving an assist".
