The team looks better when he plays, fact. He is in our top 11 outfield players, fact. Should start every game he is fit, fact.
And, yes, for those of you who are watching highlights of Europe's best teams each week, he isn't up to that standard. Yes he can be quite immobile, and yes he can foul, and yes he is inconsistent, and yes he's not as good Nico Barella or Houssem Aouar. But ffs if that's your frame of reference, you may as well give up on the team this season.
He brings balance to the team, is a good passer of the ball with both feet, and when he is on form (such as Spurs first game of the season) he can dominate that left side of midfield.
Pretty obvious imho
