I don't know if I'd agree with your assessment of Ozil on Saturday. I'm a pretty decent fan of Ozil, so take that for what it's worth, but to me he showed plenty of positivity and creativity. He'll never be a defender, but he can definitely unlock defenses. I'd love to see them play the old 4-2-1-3, with Lacazette, Auba, and Pepe up top, with Ozil right behind them. The problem is with the 6 guys behind them.
And as much as it pains me to say it, Chelsea are the most exciting team for me to watch in the Premier League. Willian and Pulisic are looking dangerous and Abraham is consistently putting it in the back of the net. Jorginho looks way more confident, almost to the point that Kante seems surplus (in case Roman is listening and wants to give him to Arsenal for free).
