Yeah but you know full well what the OP meant, mouthing off about a lad making his full debut. Next thing you’ll be complaining about folk having a go at you.
Thought he already made his first team debut? I would assume he got a good round of applause when he came off. You will always get individuals giving their opinion whether on here or in the ground. I'm sure professional footballers are aware of it and can cope with it. Incidentally, having seen the missed chances, I think although he should have scored it wasn't nailed on. I have seen far worse misses.
I personally wouldn't have a had a go at the lad. It's the club who have created the situation where he needs to play.
