Liverpool completed the transfer of Emre Can from Bayer Leverkusen on Thursday.
The Reds agreed to a deal in principle for the versatile midfielder last month, and the paperwork now has been finalized.
Can becomes Liverpool’s third signing of the summer, following the transfers of Rickie Lambert and Adam Lallana from Southampton.
“I am proud to be a part of the family and I am looking forward to playing here,” the 20-year-old said. “I will give it my best.
“LFC is a great club and the fans are amongst the best in the world. I am looking forward to the first game and can’t wait to step on the pitch for the first time at Anfield.”
Can made 29 Bundesliga appearances last season, scoring three goals for Leverkusen, in addition to seven Champions League run-outs.
