Havertz is still the weakest outfield player in Arsenal's 11. Him and White.
Yeah, I'd consider him the weakest outfield player, but that's also because Arsenal has a very strong starting 11 at the moment. If you removed Havertz from the question, then who is the weak link?
Saka - stud, one of the best wingers in the world
Jesus - not always clinical, but tremendous creativity, hold up play, and fluidity in attack
Martinelli - stud, but needs to improve decision making at times
Odegaard - stud, lot of great 8/10 tweeners, but he's up there with the best
Rice - stud, one of the best CDMs in the world
Saliba - stud, one of the best CBs in the world
Gabriel - stud, great compliment to Saliba, rare dumb moments
White - excellent foil to Zinchenko, mostly sound in defense, and offers overlap for Saka
Zinchenko - metronome to our team/tactics, which makes up for defensive shortcomings
I was going to argue with your calling out of Ben White, because he's been fantastic for us, but at the same time I don't have an easy answer. I have some critiques for certain players, but they mostly make up for their shortcomings in other areas.
