1) Marc-Andre ter Stegen (Barcelona)
Much has been made of Simon Mignolet not being good enough to be Liverpool’s long-term goalkeeper under Klopp, and an upgrade is badly needed in the summer.
While the 27-year-old is good enough to merit a squad place, his distribution, decision-making and general aura are not at the level required to be a success at such a big club.
Barcelona’s Marc-Andre ter Stegen ticks all of the boxes when it comes to replacing Mignolet, and his lack of playing time for Barcelona – he only features in the Champions League – could mean a move away appeals.
The 23-year-old is one of Europe’s most talented young ‘keepers, and his Manuel Neuer-esque ease on the ball suits Klopp’s style down to the ground.
The fact that Ter Stegen is German only adds fuel to the speculation, as is the case with any player of Klopp’s nationality.
The Barca man is young, consistent and prodigiously gifted, and while Mignolet feels a little like a throwback between the sticks, he is very much a modern-day goalkeeper.
FC Koln’s Timo Horn is another strong contender to come in and become Liverpool’s No. 1.
