Georginio Wijnaldum join Liverpool in California this weekend, after agreeing a five year, £75,000 a week contract.

Holland international midfielder Wijnaldum will have a medical on Friday, after his club Newcastle agreed a fee of £23m — which could rise to £25m, based on appearances.

Once the 25-year-old has completed the formalities of the deal, he will immediately fly to the United States to join up with his new team-mates on their pre-season tour.

Bar any late dramas, Wijnaldum should reach the club’s Palo Alto training base by Sunday evening, which will allow him four days of acclimatisation before his likely debut against Chelsea.

In pictures — the Liverpool squad arrive in California:

Liverpool are due to play their Premier League rivals in the International Champions Cup in Pasadena next Thursday.

They also play AC Milan and Roma in the States in that competition, before returning to England to face Barcelona at Wembley on August 6.

Wijnaldum would become the sixth signing of the Jurgen Klopp reign, with the Anfield manager quietly transforming the squad he inherited last season by making some significant signings.

He has spent more than £70m, and still expects to pull off at least one more deal, with a left back high on his list of priorities.

With the club not in Europe next season, that will see a heavily over-loaded squad, especially with players such as Mario Balotelli, Lazar Markovic and Luis Alberto returning from extended loan periods.

It will mean likely departures, with the midfield area coming under extra scrutiny.

Wijnaldum is an unexpected signing in a part of the pitch where Liverpool would seem to have plenty of strength.

Joe Allen looks certain to leave, with Stoke making a bid, while veteran Lucas Leiva has been a target for Galatasaray, who have opened negotiations over a potential £2.5m deal.

There has also been some speculation about the future of skipper Jordan Henderson, with Tottenham frequently linked to the combative midfielder.

Klopp currently has three players for each of his midfield and forward positions, and clearly that is overloaded given the 25-man squad restrictions in the Premier League.

The German coach welcomed back some of his international players to the squad for the trip to the States, with the likes of England's Henderson, James Milner, Nathaniel Clyne, Daniel Sturridge and Adam Lallana being joined by fellow Euro 2016 flops from Belgium.

But Klopp admitted he has a problem with the returning players behind the rest of his squad in terms of fitness, and he said: “We have to bring this fitness level together.

“At this moment I have no idea who I will play in the first game but for our first friendly game in the US I think we have 15 or 16 players who could go 90 minutes and we will see how the English and Belgian boys are.

“We have worked with different groups. The good thing with a training camp is you have nothing else to do so we can be fully concentrated on the things we have to do.”

One player who has not flown out to the States is Jon Flanagan, with the defender remaining behind in the UK to consider an offer of a one-year loan to newly-promoted Burnley.
