Yes right the lad off after an error and ten minutes on the pitch. He has shown enough previously to see that he has great potential.
I think he's got enough to make it as a pro, but not at Premier League Level. As others have said it's easy to see why Pulis doesn't play him.
I didn't see his briefing before he came on, but it's inconceivable that he didn't get one. He's also played a lot of games at under 21 level, so he should be well aware of the protocol. From what I've seen of him at first team level, he's not a team player & I think he demonstrated that again today. There was an easy option of a pass, but he wanted to make a name for himself, so he chose the selfish option & paid the price.
IMO it will be sometime before we see him again.
