Liverpool came up against Manchester United at Old Trafford last weekend.
As you can see pictured below, Elliott watched the aforementioned Premier League fixture from home.
When the image was taken, the youngster was standing right in front of the television, which does suggest that he was heavily invested in the match.
Elliott grew up following Liverpool. Therefore, the midfielder is a supporter as much as he is a player.
