For me personally, it has nothing to do with potential,will he or won't he get better. If he stays like he does right now he will win us games, give plenty of assists and have teams putting 2 players on him at times which will open up space. He lasted the full 90 yesterday again, another game under his belt as it's just fitness and decision making which he will get sharper at.
Watch the ball he plays to Barkley for our goal, doesn't even need to look where Barkley is, plays it on instinct because he has a picture of what's going on around him.
Won't always be boss, but easily an absolute steal at 4m and I would persist with playing him in as many games as possible because he's going to win us games.
imo
