"Apart from losing home ground advantage, we are not sure if we can afford to play in a neighbouring country, which is an expensive logistical exercise," Rukaro said.

McCarthy extends Rovers deal
Meanwhile Benni McCarthy, South Africa striker, has agreed a new three-year contract with Blackburn Rovers, manager Mark Hughes confirmed on Friday.
The 30-year-old, who has scored 11 goals this season, has now committed until the end of the 2010-11 season.
McCarthy, Blackburn's top scorer after joining from Porto last season, had been in negotiations with the club for a number of weeks.
"I think it's actually done now which is good news for us," said Hughes.
McCarthy scored 24 goals in his first season at the club last year.
Although he has not replicated that form this term, often playing a secondary role to new star man Roque Santa Cruz, the South African has remained an important member of the Rovers side.
His new deal will take him beyond the 2010 World Cup, in which he will hope to play a role in his homeland.
