Djourou: I chose Birmingham because of Bruce
The 20-year-old Swiss international defender is the latest of Arsene Wenger's youngsters to agree a loan deal with Blues.
He said: "There were a lot of clubs interested, but I was keen to work with Steve Bruce.
"He was a centre-back and he's been passing on a lot of tips. He's a fantastic coach and I'm sure he'll help me a lot."
