5. Timo Horn
Horn is just one of the many impressive German ‘keepers around that would get into most national sides but can’t get into his own because of the ever-impressive Manuel Neuer. Nevertheless, Horn has been part of an FC Koln side that have captured the imaginations of many Bundesliga onlookers and West Ham should get themselves on that list, too. At just 23, Horn could easily perform for another decade to come.
