Jose Mourinho says Manchester United shouldn’t have given Lionel Messi so much room at the Nou Camp.
Messi scored two first-half goals on Tuesday night - to prevent any chance the visitors had to overturn the deficit they had prior to the match - as Barcelona cruised to a 3-0 win (4-0 on aggregate) to seal a semi-final spot in the Champions League.
And, former United boss believes Messi should have been put in a cage.
Speaking to Russia Today, Mourinho said: "Messi's position is easy to understand but it is not easy to create a cage to control him.
"He comes from the right, then stays in the middle, then [Ivan] Rakitic goes right and allows him to stay in the middle. It's very difficult.
"Manchester United in the first match, zonally they occupied that area very well - but I think in this match that they started with a different perspective.
"In front of the defensive line was only Fred. That's the area that Messi comes to get the ball and when Messi has the ball... one, one, one…you are dead.
"That's why I never liked individual man-on-man against Messi. Messi's a cage, you have to create a cage.
"But Barcelona is Barcelona, they have better players than Manchester United and I think it's normal they won."
