Armchair Expert 

Someone who acts like they know the ins and outs of a sport despite never having actually participated in it and having accrued all of their knowledge of the game from watching matches on TV.

Armchair experts typically criticise players way too harshly or referees/umpires for decisions that are very hard to get right, even though most armchair experts would fail to run 100 metres without passing out.

Man 1: "How is he not getting to that ball?!"
Man 2: "There's no way he can possibly get to that, you're such an armchair expert.
