Is havertz a miss? Absolutely.
But don't forget the moment he got injured, Arteta managed to get the board to sign Eze
If Arteta had started his first eleven properly, Havertz injury excuse would not be mentioned
Eze and Martinelli starting instead of Merino/Trossard
Trossard & Saka to come on for Martinelli & Madueke, while using Merino as the Gyokeres replacement if required
