Prime Minister David Cameron joked Friday that he will do his best to avoid his German counterpart Angela Merkel at the G20 summit when the two nations meet during the knockout stage at the World Cup.

"I'm not sure if that will be safe. We might get a bit carried away," Cameron chuckled on British breakfast TV show, GMTV.

"I will be there cheering along with everyone else."

Asked about the World Cup on Sky News, Cameron said he would resist the urge to mock his French and Italian counterparts, Nicolas Sarkozy and Silvio Berlusconi, over their teams' dismal first round exits.

The British Premier also revealed how Berlusconi was "claiming Capello," reference to England's Italian coach Fabio Capello, who is technically the only Italian left in the South Africa showpiece.Cameron said he thought England would win Sunday's crunch encounter in Bloemfontein.

But he said he wanted to avoid the "stress of penalties" -- the nightmare scenario that haunts all England fans, with the team having lost its two previous penalty shoot-outs with Germany in major competitions.
