Manchester City signing Jerome Boateng couldn't care less what brother Kevin-Prince thinks of him!

The pair have not on speaking terms over Portsmouth midfielder Kevin-Prince's clash with Chelsea's Michael Ballack at the FA Cup final.

"Kevin thought I should have criticised Ballack and defended him," Jerome said.

"Now I don't care what he does. It really doesn't interest me."

The pair will come together this week when Germany face Ghana in their final World Cup group game.
