Liverpool manager Jurgen Klopp has predicted that Georginio Wijnaldum will prove to be a "great player" for the club.

The 25-year-old midfielder completed his reported £25m move to Anfield from Newcastle United this afternoon, putting pen to paper on a five-year deal at the club.

The Netherlands international will now fly out to join his new teammates on his pre-season tour of the United States, and Klopp is looking forward to his arrival.

"I am so happy that we have got him and he can join us now in the USA. I think he can be a great player for us. He has already shown some really good moments in his career but the most exciting and important thing for me and my staff is that there is still so much extra to come from him," he told the club's official website.

"When I talked to him I could tell that he knows we have to work together to get this level out of him to all be successful for the team. He has played a lot for his country already, been captain at a young age in Holland and also been involved in a tough Premier League season so this experience gives him a good foundation for the challenge here - which everybody knows is huge.

"He can play a few positions for us and players that come through the Dutch system usually have a good tactical understanding and flexibility. That's really important. I can't wait to get him on the training pitch and for the fans to see him play in a Liverpool shirt."

Wijnaldum could make his competitive debut for Liverpool when they take on Arsenal on the opening weekend of the Premier League season.
