Jack Wilshere believes Arsenal must employ a physical style of play against Barcelona when the two sides meet in the Champions League at the Emirates Stadium on Wednesday night.
While the youngster insists the Gunners have learned from their defeat to the Catalan giants in the competition last year, he has called on them to "be a bit nasty".
"We've got to change our game a bit to play against Barcelona," Wilshere said, according to the Daily Mail.
"We'll learn from last year. When we've got the ball, we've got to keep it as well as they can. We need to get in their faces and win the ball back and, if you like, be a bit nasty with them.
"There's no point one of us going after them. We have to press as a team and get the ball back."
At a personal level, Wilshere's stock has risen in recent times and he has managed to make consistent appearances for the Gunners this season, and even made his full England debut during the victory over Denmark last week.
Now the 19-year-old wishes to gain valuable experience playing against the likes of Xavi and Andres Iniesta.
He added: "I watch Barcelona playing in La Liga and I watch Xavi and Iniesta just run the games. That's what I want to learn from and do myself. It will be great to play against them.
"It's been a brilliant week for me, probably one of the best of my life. I will never forget that England game.
"Playing for your national team is amazing. Playing with the players I played with was amazing. Frank Lampard was great.
"I'm comfortable in the role I played for England. It wasn't really just a defensive role. I spoke to Frank before the game and he said, 'If you want to go forward, go forward', and vice-versa. It was similar to my role at Arsenal."
