As far as goalkeepers go, the 2020-21 UEFA Champions League campaign was an interesting one. Some of the usual suspects like Marc-Andre ter Stegen and Alisson Becker didn't really make the headlines, as their teams were eliminated before the business end of the tournament.In stark contrast, a handful of other goalkeepers made a massive impression on the grandest stage, with Chelsea's Edouard Mendy the pick of the bunch. The Senegalese shot-stopper replaced Kepa Arrizabalaga between the sticks and quickly made a massive impression, as he won the UEFA Champions League in his debut season at the club.May 2015, unemployed and looking for a job after being released by Cherbourg.May 2021, first African goalkeeper to win the European Cup in the Champions League era.Edouard Mendy deserves the best 🏆🔵 #CFC pic.twitter.com/MeOW1eWQda— Fabrizio Romano (@FabrizioRomano) May 29, 2021A goalkeeper's primary job is to save shots, but in this day and age, they are also expected to be useful with the ball at their feet.
