Apologies Román Dylan , but I think your opening post is nonsense.
What the hell is the point in having a youth system if we don't try out the products of it? You can't judge whether or not a player is PL capable based on 20 mins of a cup tie.
You can when you see that he's never had a great goal return. Last year for example at league 1 Yeovil he only got 4 in 24. Lots of people didn't like Pav but he had a far better goal return (not saying Pav is our saviour just an example). The fact is he's not getting to the point where he's too old to be scoring so few goals in league 1. I wish I was wrong but he was invisible for most of his time against Championship opposition.
