Arsenal manager Arsene Wenger was full of praise for defender Calum Chambers after the North London derby against Tottenham Hotspur.
The 19-year-old joined the Gunners during the summer transfer window and with Arsenal suffering injuries in defence he went straight into the regular team.
"He has been remarkable in every position," Wenger told the club's official website.
"He has an unbelievable engine. He goes and goes. It's not often that you see that quality.
"His yellow card was very harsh and the one against Villa was very harsh as well. I've told him to be keen and committed and I think he had a good game overall.
"I'd consider playing him in midfield but I don't know about Wednesday [against Galatasaray] because I only have four defenders at the moment."
