Current Manchester City boss Pep Guardiola once left Sir Alex Ferguson shaking on the sidelines after his famous Barcelona team broke Manchester United.

It was during the 2011 Champions League final when Barca ended up winning the game 3-1, smashing the Red Devils in the process.

The Blaugrana dominated the game and five minutes before full-time, cameras caught Sir Alex shaking in anger on the bench.

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

Curiously, Ferguson was never able to defeat Guardiola in his time as United manager. Further, he even stated that no other team had dominated his side like the La Liga outfit had.

“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,” he told The Guardian.

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

Some might consider Lineker’s comments a little too much. Guardiola joined the Premier League in 2016 and he’s done good, but that doesn’t mean he’s the most influential boss there considering he’s only managed in England for four years.
