Olympique Lyon defender John Mensah is delighted with his loan move to Sunderland.
The Ghana international told safc.com: "I'm very delighted to join Sunderland today, it's like a dream come true for me because it's not easy to play in England.
"I want to tell my fans that they should not expect magic from me but that I will be giving my best.
"I have a lot of experience from Italy and Europe, while I have played a lot of games for my country and competed in the World Cup and the African Nations Cup.
"Because of this it is not difficult for me to play in England. Now I hope I can do well here in Sunderland and I will listen and do whatever the coach tells me to do."
