fantasist 

A person who fails to grasp the difference between reality and what they imagine to be true in their own mind.

Like Spurs fans that never actually go to games but think their opinion about football is relevant.

Lee supports Spurs and thinks they are better than Leicester. Lee is a fantasist.
