Carlsen moved to the very top of the Fantasy Premier League after his captain, Mohamed Salah, scored twice for Liverpool on Saturday, earning 32 points.
Contacted by British newspaper the Guardian, Carlsen put his success at the game down to both luck and statistics.
“In fantasy football I’m both an optimist and an Optamist,” he told the newspaper, referring to Opta, the statistical data provider which can be used to track the form of footballers.
Although the Norwegian could lose his spot on the Fantasy Premier League perch as soon as Monday night, it is still a remarkable achievement given the millions of participants in the game.
Carlsen, the current World Chess Champion considered by many to be the greatest chess player of all time, saw fit to change his Twitter biography to reflect his fantasy football success.
“World Chess Champion. The highest ranked chess player in the world. Current (live) #1 Fantasy Premier League player,” it read on Monday.
Fantasy Premier League involves selecting a squad of players from the 20 English Premier League clubs using a limited budget. The players are awarded points after every match depending on their performance.
Fantasy league players can select, trade and drop players from their teams throughout the season.
The game is hugely popular in Norway, which had 8 players in the overall top 50 at the end of the 2016-17 season.
