The midfielder is on-loan from the Gunners.
"He's picked a very brave decision for me," he said.
"He's gone to a smaller club, he's gone somewhere where there's not everything here, there's not everything done for him.
"It's slightly old fashioned in the way that it's like a step back in time for him compared with other Premier League clubs and I think he deserves credit for that.
"I believe our environment can be good for him because the players work incredibly hard, they push themselves to improve and I think that's a healthy environment for any footballer and that's why I think he decided to come here ultimately."
