Sadio Mane could make his Liverpool debut as early as next week when they face Tranmere Rovers in their first pre-season friendly at Prenton Park on Friday.

The £30 million forward signed a long-term contract with the Reds on Tuesday to complete a transfer from Southampton and become Jürgen Klopp's fourth signing at the club as a result.

He will join up with his new teammates this Saturday when the squad return to Melwood for pre-season training, but he and the Reds' other summer signings will likely make their first appearances - although uncompetitive - just six days later against Tranmere.

Although six of Liverpool's 12 internationals at Euro 2016 have been eliminated as the tournament nears the quarter-final stage, which begins on Thursday, none will be return from international duty for at least a few weeks.

Klopp has previously suggested he would grant those involved with their national teams, including Philippe Coutinho who played for Brazil at the Copa America, at least three weeks off before they are expected to join up with the rest of the Liverpool squad.

That means the likes of captain Jordan Henderson, striker Daniel Sturridge and midfielders Emre Can and Coutinho are unlikely to return to club duties until the tour of the United States, which Liverpool jet off for towards the end of July.

Nevertheless, starting off at Tranmere, Klopp still boasts a strong contingent to field in their first few friendlies. Among them are defenders Dejan Lovren, Alberto Moreno and Mamadou Sakho and forwards Roberto Firmino and Danny Ings, who is returning from a nine-month injury lay-off.

Mane, as well as Marko Grujic, Joel Matip and Loris Karius who join up with Liverpool for the first time this coming weekend, will all also hope to feature against the Reds' close neighbours Tranmere in their first meeting since 2008.

After that, Klopp's squad take on Fleetwood Town, Wigan Athletic and Huddersfield Town before flying out to the US for a three-game schedule which sees them face Chelsea and AC Milan in the International Champions Cup and AS Roma in an unrelated clash.

Upon their return to England in early August, they face Barcelona in a showpiece friendly at Wembley Stadium before taking on Klopp's former club Mainz in Germany the next day, which is likely to see the squad split into two different teams.

The Reds will hope to use their undoubtedly strenuous pre-season as a means to build fitness levels up towards a strong start to the 2016-17 Premier League season, which they get underway with a tough trip to Arsenal on August 13.
