#3 Kevin Trapp
With just two starts in the league for Paris Saint-Germain this season, Kevin Trapp has been struggling for game time, as manager Unai Emery prefers Alphonse Areola over the German international. It's a decision that could see the 27-year-old make himself available for a move in search of regular first-team football and Liverpool could just be the perfect destination for him.
Trapp can easily be seen as an upgrade on Mignolet and compatriot Karius, thanks to his shot-stopping ability and experience from playing with and against some of Europe's best defenders and attackers.
That quality alone could be a huge plus for Liverpool, as Trapp would demand only the best from his back-line, while the fact that he is also strong in penalty situations is a vital asset to have. Reds fans will be hoping that the prospect of playing for his fellow countryman Klopp is an appealing one.
