"It won’t take more than a week before this is sorted out," said Bonnesen.
"It might even be at the beginning of the week. Christian is Roy’s man. He will be playing as a defensive midfielder."
"Christian would be a perfect addition to most of the big clubs in Europe, so he will certainly fit in here," Agger told the Liverpool Echo.
"He is a top player and will make us stronger. We need to have big signings so we can compete and he is one of those players. Christian will improve the team. But we need more improvements if we want to be at the top of the league this season."
