Oh he would play , no doubt but he's no where near the finished article.He played over 1800 league minutes, so over half of those available at just 18 last season mate, only Saka and Greenwood have matched that from under 20s the past 6 years.
If he signs he'll play the vast majority of games this season
That's ok provided he plays like a £40 million player straight away. Can he ? That's the question.
Buying a player to develop is great but not when you lash a huge proportion of your budget on them and need them to perform straight away.
