The way we play our forwards (Kane, Son, Vinny, etc.) get maybe 1-3 chances a game to convert. If they convert those 1-3 chances we talk about how lethal they are and how they're the best finishers in Europe. When they don't finish their 1-3 chances, they're shit and not worth playing for Spurs.
The reality is every forward in world football will miss chances and struggle given 1-3 chances per match. The best strikers miss chances, they just miss fewer of them than poor strikers. That's why the best teams try to create a lot of chances for their strikers.
Vinny got a single clear cut chance and he missed it so our fans slag him off. Bergjwin got the same dose in the Liverpool match, he missed on his ONE chance.
Maybe instead of slagging off our players when they miss their one chance a game, we ask that our system be changed so they have more than one opportunity.
