Oxlade-Chamberlain is hoping to enjoy a successful Euros with England.
"You donâ€™t have to look any further than Xavi and Iniesta, do you?" Oxlade-Chamberlain told the Mail on Sunday.
"If youâ€™re clever enough on the ball and your touch is good enough, players like that wonâ€™t allow themselves to get into 50-50 physical battles.
"If, say, an Iniesta got into 50-50 battles with big, tall central midfielders, I think eight out of 10 times he would lose. But heâ€™s cleverer than that. He uses his first touch to get in front of the player, so the player will either have to foul him or leave him alone to get by him.
"You have to adapt the game to the way you are and I think that comes naturally. Training every day, whatever your physicality is, you have to adapt to play around that.
"Itâ€™s a footballing lesson for anyone, just to watch the way Barcelona play. I do watch Lionel Messi in particular and Iniesta and even Cesc Fabregas. Thereâ€™s always a lot you can learn from others."
