You really think Messi took him to the cleaners in both legs?
At the Nou Camp, Liverpool had the better of the first half with more chances and Barca's goal did not involve Messi.
The first time Messi opened them up was after 65 mins and even then it was a pass as his path to goal was blocked.
It was only after 75 mins that he was amazing.
"Liverpool played well in defeat but couldn’t take their chances on a night when Luis Suarez and Leo Messi put them to the sword."

Anfield was total domination by Liverpool you must be the only person in the world who thinks Messi took them to the cleaners there.

It's not just Messi in the vid, btw, as you see a who's who of top players getting dispossessed many times by him being a massive roadblock in their path or succesful dispossessions from behind, when they are past him, as he uses his long legs to get a toe poke the ball to his defenders. You also see him use his height to win headers and physicality to knock players off the ball. Torreira, for all his ability, cannot do any of these due to his stature.
I actually agree with you that he is not other worldly special as we can easily find another DM with his attributes who could do the same.
