Chelsea Transfers: 5 Under-The-Radar Keepers To Replace Thibaut Courtois

It would be pretty hard to convince Timo Horn to leave FC Koln, yet stranger things have happened. The German shot-stopper has been with the club since the age of nine and is a loyal servant; he supported the team even before he joined them in 2002 and isn't looking to leave.

Horn was offered the chance to join Liverpool at the age of 15 and rebuffed the proposal, choosing to remain with his boyhood club until this day. Koln were relegated from the German Bundesliga last season, but the player has remained steadfast, even signing a new deal with the club in the wake of their demotion to a lower tier.

The 25-year-old, who won Olympic silver with Germany in 2016, is an impressive guardian of the goal - it's just a pity he's playing in a team that concedes an unhealthy number of shots. On the flipside, though, he's quite used to being under pressure and seems to thrive therein.

As mentioned before, getting this keeper to Chelsea would take some doing. But he's definitely worth considering.
