I understand what you’re saying but a teenager in his first season at Premier League level can’t be seen as a replacement for your most reliable midfield option of the past five years. He’s a talented kid for sure but it’s a stretch to think he could be as dependable as Gini already.
If Naby, Ox and Hendo weren’t as prone to injuries and Milner wasn’t 35 then maybe you can take that gamble. As it is, we’ve been unlucky but you can hardly say the warnings signs weren’t there.
