#1 The airlines and the GOAT
Marc-Andre ter Stegen and Leo Messi are arguably the best players of the team.
Ter Stegen making 79 saves this season, is one of the best goal keepers in the world. He has been a wall for the team. Named as "Stegen Airlines" by the Barcelona twitter account, he does everything to not allow the ball to go into the net.
Leo Messi, has scored 29 goals and providing 14 assists in just 29 matches this season, has been the key player in Barcelona wins. He has always performed and will always perform. He is the greatest player on the planet. He is on the top of charts at both goals scored and assists provided by a player in Laliga.
Both of them have been in great form and will have to be at their laser sharp best till the end of the season to lead Barcelona to win the treble.
