Olympiacos have paid tribute to new Liverpool signing Kostas Tsimikas.

The 24-year-old defender has signed a five-year contract with the Reds, and will provide competition for Andrew Robertson at left-back.

The Reds will pay Olympiacos an initial fee of around £11.75m, with Tsimikas wearing the No.21 shirt which was previously worn by Alex Oxlade-Chamberlain before he switched to No.15 last year.

Olympiacos have congratulated Tsimikas on making the switch to Liverpool, and also wished him the best for the future.

“In 2014 #Tsimikas joined the @olyfcacademy," the Greek club wrote on Twitter via their English account.

“Today we are proud to announce the transfer of our "Tsimi" to the English Champion & current European & World Champion @LFC!

“We wish you every success Kostas, you will always be a member of our red-and-white #family."
