Hamburg defender Jerome Boateng says his family is excited about him moving to Manchester City.

Boateng is the kid brother of Portsmouth midfielder Kevin-Prince Boateng, who is likely to quit Fratton Park at the end of the season.

While Jerome could go to South Africa with Germany, Kevin will be playing for Ghana in the same World Cup group.

"I don't know how dad's going to work out who to support, but he is as excited as me and Kevin," said Jerome.

"Ever since Germany and Ghana were drawn in the same group, Kevin and I have been sending each other messages. The texts have been flying. The handshake before kick-off is going to be a special moment, but after that he's just another opponent. Family will count for nothing, and if I have to kick him, I will without even thinking.

"We've faced each other once before, when he was on loan at Borussia Dortmund near the end of last season. I was on the losing side that day, but I have told him I will have my revenge in Johannesburg."
