Usually just comes down to agendas, as mentioned. I can't stand Ndombele. I think he's over-rated, nowhere near as talented as some try to make him out to be and on top of that his attitude and mentality are fucking awful. But if he has a good game, and as a Spurs fan I want him to have good games, then I'll happily give credit.
If Gil plays well against poor oppositions he looks a prospect, yet if Winks does it's only because the other team is so shit. If Harry scores against poor opposition, as all the top strikers around do, it's only because he's padding his stats and is something that should be criticised.
This place is absolutely mental.
