After Liverpool famously knocked FC Barcelona out of this season's UEFA Champions League despite losing the first leg 3-0, one of their key players has now revealed why Lionel Messi was furious with him and called him a donkey.

James Milner clashed with Messi in the first leg at the Camp Nou, with the Reds midfielder shoving the Argentine off the pitch in the first half of their 3-0 defeat.
The FC Barcelona captain was not happy with his opponent's antics and had a go at him as they walked down the tunnel at half-time, Milner recalled.
"He wasn't happy," he told the Daily Mail.
"He was giving me plenty in Spanish going down the tunnel at half-time as well. He was calling me 'burro'. It translates as donkey but I think it's also used in Spanish football as a general term for someone who goes around kicking people.
"I asked him if he was all right, but he wasn't having it. I don't think he realised I understood his Spanish.
"He said: 'That foul you did, that's because I nutmegged you.' I left him to it at that point and went into the changing room.
"Look, I've only got admiration for him. He has earned the right to say what he wants."
Milner was famously nutmegged by Messi at the Camp Nou when he was still playing for Manchester City in 2015, with a video of the incident going viral on social media afterwards.
However, the Englishman has insisted that, as a player, you cannot be scared to be made to look like a fool by Messi.
"The stuff he did in that game, stuff he has done his whole career, it makes him tough to play against. If you try and stop him, you can't be scared of being made to look foolish," he added.
"I've done it. I've been nutmegged by him and it has been viewed a million times. I wasn't the first and I won't be the last. He's an incredible player.
"But with players like that, you have to let them know you're there and not let them have everything their own way. You just need to try to disrupt their rhythm.
"You don't want to hurt him but it's a physical game and, if he's running the game, you try and knock him out of his stride. It's part of the game, the mental side."
Liverpool will face Tottenham Hotspur in the UEFA Champions League final on Saturday night, when they will try to lift their sixth European Cup.
