"I think it is going to be a real big change (from December)," Wijnaldum told reporters after Liverpool's 0-0 draw against Bayern Munich in the Champions League.
"Since the new manager came in there is a new flow, they played good games and have won a lot and that is building confidence in the team.
"It's also a home game for them so they will have a lot of confidence as they don't have the problems they had before. It is going to be a difficult game but I'm looking forward to it."
