#5 Peter Gulacsi

Liverpool have been going through a goalkeeping headache ever since the departure of Pepe Reina. Simon Mignolet, Loris Karius, Brad Jones, Danny Ward and Adam Bogdan have stood in goal for Liverpool in the last four seasons.
In the same summer that Reina went on loan to Napoli and Mignolet arrived, Liverpool sold Hungarian keeper Peter Gulacsi to Austrian club Red Bull Salzburg. From there, he went on to play for their sister club RB Leipzig when the German club was in the second division.
He helped the club earn promotion to the German top flight but only became the undisputed number one keeper at the club last season while playing in the Bundesliga. The 27-year-old started 33 league games out of 34 as Leipzig finished second and qualified for the UEFA Champions League.
Gulacsi never made an appearance for Liverpool but is now playing for a club in the Champions League. Maybe, Liverpool gave up on the player too soon.
