Liverpool have signed midfielder Wataru Endo from Stuttgart for a fee of around 19m euros (£16.2m), subject to a work permit and international clearance.
The 30-year-old Japan international has agreed a four-year contract.
Liverpool have brought in Endo after missing out on Ecuador international Moises Caicedo and Belgian midfielder Romeo Lavia to Chelsea.
Endo can also play at centre-back but has been signed primarily as a central defensive midfielder.
“It feels amazing,” he said. “It’s always been a dream to play in the Premier League and with one of the biggest clubs in the world. It’s a dream come true for me.
“I think I can help this club defensively and I will have good organisation in the middle.”
