N'Zogbia has told him to watch out for dirty tricks from Premier League defenders.
He said: "With the size he has and the way he can hold the ball for the team, he's important. He's made a big impact but he's a young kid and this is his first year in the Premier League.
"So he'll still have to learn how to play against different defenders. They are really strong and it's going to be a massive challenge. I told him that in England the defenders won't laugh at you, trust me, you'll end up with a head cut or something.
"He has to make sure that every single ball he goes for he has to go for it 100 per cent. Now he knows. He's brave enough to do that though - he has the size and the strength.
"If you have a bad day, you have to make sure you forget about it."
