Mikel Arteta has described Arsenal teammate Serge Gnabry as being like "a little boxer" following their victory over Tottenham Hotspur on Saturday.

The 18-year-old German winger was one of the star performers in the North London derby as Arsenal moved into the fourth round of the FA Cup thanks to a 2-0 win over the old enemy at the Emirates.

"I think he's got a lot of quality," Arteta told the club's official website. "He's got something not many players have in this team, which is pace and skill to go and beat people.

"That's why the manager played him - three up front is something that helps us be more incisive. We want to go behind [the opponents] and get into one versus one situations. Gnabry is very good like that and I'm very pleased for him because I think he did really well.

"He's like a little boxer, he's a little fighter. He's good. He's got a lot of character as well, the lad doesn't get intimidated either because it's a derby. His character is great. You see it in training. Technically, he is very good but he's got something about him as well. He doesn't mind when he gets kicked, he gets up and goes for the next ball. He's quite brave."

Arsenal will host Coventry City in the next stage of the competition.
