​Manchester United's Alexis Sanchez has admitted that his team were powerless to prevent ​FC Barcelona's Lionel Messi from knocking the Red Devils out of the ​UEFA Champions League.

After leading 1-0 from last week’s first leg at Old Trafford, Barcelona’s greatest ever goalscorer ​ended the two legged tie with two goals in the space of four first half minutes at the Camp Nou. His first goal was mesmerising and his second goal was courtesy of a crazy David De Gea mistake.

United missed several great chances early on in the tie before Messi took the game in his own hands and Philippe Coutinho, later, putting the tie to bed with a sublime goal.

As reported by ​Metro, speaking after the game, Sanchez, who himself got a few minutes of action against Barcelona said, "They played very well. We had very clear chances, but this is football, this is the Champions League."

He continued, "If you get something wrong or fail, then the other team gets on top of you. That’s what Barcelona do. The truth is that the first goal was a very nice goal. Leo is Leo, we all know what we can do."

Sanchez signed off by stating, "It’s the same as always. Leo, he is very happy at Barca. He maintains this high level of performance and the team is also playing well."

The Chilean was making his return to action against his former club after six weeks out with a knee injury and was denied a goal on his comeback courtesy of world class save from Marc-Andre ter Stegen.
