Real Madrid legend and former teammate of Cristiano Ronaldo, Iker Casillas, has labelled Lionel Messi the GOAT (Greatest of All-Time) ahead of the 2019 Ballon d’Or ceremony on Monday. The star goalie made this claim in a tweet where he was talking about Barcelona’s 1-0 win over Atletico Madrid.

Messi’s only goal proved to be enough on the day to give the La Liga giants all three points. The fact that the match was played on the Ballon d’Or eve meant that everyone had to talk about Messi’s performance who is, in fact, one of the frontrunners to win the award.

While explaining how to make a football team that can win anywhere in the world, Casillas explained that one needs to have a top-rated goalkeeper and a GOAT player and Barcelona have both of them in Marc-Andre Ter Stegen and the Argentine great Lionel Messi

“Formula for football: goalkeeper (top) & player (GOAT). Today Barca took the three points at Wanda Metropolitano. Atletico have played well but lacked composure in front of goal. Blaugrana remain top of the league. Atletico have to fight for the Champions League zone,” Casillas tweeted in Spanish, suggesting that he believes Lionel Messi is the GOAT (Greatest of All-Time).
