#3 Loris Karius
Karius caught Man City's eye when he was playing for Germany under 16ys against Azerbaijan in 2009. He was invited to Man City for a trial, and he signed in July 2009. Sadly he never came close to the first team and he left for Mainz.
At Mainz, he had great success where he became one of the best keepers in the Bundesliga. He was particularly impressive in the 2015/16 season where he was named the second best keeper behind Manuel Neuer.
He then signed for Liverpool. He struggled at first and was the number 2 behind Simon Mingolet. However, in the 2017/18 season, he became the number 1 and had a fairly good season for most of it, It was in the last game of the season that things changed. It was against Real Madrid in the Champions League Final. He made two huge mistakes which lost Liverpool the match.
This resulted in him leaving the club to go to Beskitas.
