He spent the second half of last season on loan with Valencia, a team he joined after signing with Liverpool.
On social media, Mamardashvili shared his thoughts about his time at Valencia, saying: “Many thought I was just on trial, and I... tried.
“It wasn’t easy, I made a lot of mistakes and there were a lot of defeats. But even when I was quiet outside, I was fighting inside.”
He acknowledged that the competition at Liverpool will be tough, but he is ready to take on the challenge.
