BUCHAREST, Sept 18 (Reuters) - Steaua Bucharest's vocal owner Gigi Becali has ordered his team's coach Gheorghe Hagi to change the line-up for Wednesday's Champions League Group H match against Slavia Prague.

'I want striker Romeo Surdu and midfielder Valentin Badoi to start the match in Prague,' Becali told reporters on Tuesday. 'Hagi will leave if he fails to make them play.'

At the weekend, Becali blamed Hagi for the team's 0-0 draw against Rapid Bucharest, when he did not use Surdu or Badoi.

'I wanted to change the former great player Hagi into an even bigger coach Hagi but he fails to listen to me,' Becali said.

Hagi declined to comment.

Becali has threatened to sack the former international before. Last month, he complained that Hagi had not stuck to the line-up he had written out for him in a match against CFR Cluj. Hagi responded then by saying he wanted to stay at the club.
