Mainz goalkeeper Loris Karius has signed a long-term contract with Liverpool after joining for a £4.7m fee.
But who is the German 22-year-old who has become Liverpool's second confirmed arrival of the summer and will he displace Simon Mignolet as first-choice keeper?
Here, we take a look...
Name: Loris Karius
Karius' spent his youth at a host of German clubs including Stuttgart, and also spent two years in Manchester City's academy between 2009-11, where he featured for the under-18 and under-21 sides.
He then switched on loan to Mainz in the summer of 2011, before completing a permanent move in January 2012, and went on to make a host of appearances for their reserves.
I spoke to the manager and I had a good feeling afterwards because he told me what he wants to do with the club and with the players
He made his senior debut later that year at the age of 19 before going on to establish himself as their first-choice goalkeeper.
Karius played every game of the 2015/16 season for Mainz, keeping nine clean sheets in the process as they finished sixth in the Bundesliga.
He has also appeared at every youth level from under-16s upwards for Germany, but his appearances have been limited as he has often played second fiddle to Barcelona goalkeeper Marc-Andre ter Stegen.
Liverpool goalkeeper Simon Mignolet may face a fresh challenge from Karius
Style of play
Karius shows a calmness under pressure when on the ball and possesses good composure with his feet, an area where current No 1 Mignolet has often fallen short at Anfield.
He may be two inches shorter than Mignolet, standing at 6'2'', but is more than adept at dealing with crosses and shows a good command of his area thanks to his aggressive starting position - much like fellow German Manuel Neuer.
He is also a superb shot stopper and his long-range kicking, which was previously an area of weakness in his game, has improved greatly over the last year.
