Ragnar Klavan undergoes Liverpool medical ahead of £4.2million switch from Bundesliga outfit Augsberg

LIVERPOOL are on the verge of signing Augsberg defender Ragnar Klavan as the £4.2million Estonian undergoes a medical.

Jurgen Klopp wants the veteran centre-back as cover, with Mamadou Sakho and Joe Gomez injured and Tiago Ilori in Portugal’s squad for Rio.

Klavan, 30, has won 108 caps for Estonia and four years of experience in the Bundesliga.

Former Dortmund boss Klopp sees him as filling a similar role as a back-up option and leader that Kolo Toure occupied before his exit.

The Reds are expected to announce Klavan as their fourth signing of the summer tomorrow.

Sadio Mane has already arrived in a £30m deal, with Joel Matip and Loris Karius arriving from Germany as Klopp uses his knowledge of the country.

First-choice centre-back Matip manage to dodge a serious injury to his ankle in Sunday’s friendly win at Wigan.

The Cameroon international, who joined on a free from Schalke, suffered bruising and is set to miss the clash with Huddersfield.

But he will travel to America with the rest of the squad for their pre-season tour.
