Liverpool are set to activate an extension clause in Dejan Lovren's contract.

The centre-back is the subject of interest from clubs like Zenit St Petersburg - but the Reds have an additional year option that the ECHO understands is in line to be taken up at the end of the transfer window.

Russian Premier League champions Zenit and others believe that Lovren only has one year left in his contract.

However, with Liverpool poised to activate the Croatian's additional year option, it will mean he is effectively tied to the Reds until summer 2022 which may have an impact on his price tag.

Lovren, who arrived at Anfield from Southampton in 2014, was the subject of interest from both Roma and AC Milan last summer but a finalised deal never materialised.

Should the 31-year-old depart this term, he will do so with the best wishes of all at the club after a committed six years of service.

Lovren has so far made 185 appearances for Liverpool, scoring eight times and providing four assists from the heart of defence.
