The Time Pep Guardiola Left Sir Alex Ferguson Shaking

Pep Guardiola once left Sir Alex Ferguson visibly shaking on the touchline after his Barcelona side dismantled Manchester United.

It was the 2011 Champions League final and Barca ended up winning the game 3-1, but the scoreline flatters United.

The Catalan giants dominated the game and five minutes before full-time, cameras caught Sir Alex shaking in anger in the dugout.

The video has gone viral after Gary Lineker's controversial comments stating Guardiola has had the 'most positive influence' out of anyone in English football.

Fans on Twitter were quick to comment on the clip.

Pedro, Lionel Messi and David Villa all scored as United fell to defeat against Barca for the second time in three years.

Interestingly, Ferguson never managed to defeat Guardiola in his time as United manager.

The Scot even conceded that no other team had dominated his side like the La Liga outfit had.

He told The Guardian: "It's not easy when you've been well beaten like that to think another way. No one has given us a hiding like that. It's a great moment for them.

"They deserve it because they play the right way and enjoy their football."

Perhaps Lineker's comments about the Spaniard's impact on England are true.

There's no doubt Guardiola's arrival at Manchester City in 2016 has seen an increase in teams playing a brand of attacking football.

But many will argue it's too early to label him most influential considering he's only managed in England for four years.

Which manager do you think has had the biggest impact on English football?

Sound off in the comments below.
