Definitely agree on the automatic starter bit. But you have to look at the competition. We'd only have two natural wingers in Bailey/Nelson whilst the others are strikers or attacking midfielders. Mhki, PEA and Lacazette look woeful on the wing so I wouldn't trust them. I reckon Wenger will somehow force one of the strikers onto the wing with Mkhi playing tho which is the wrong way about it.
Yeah, Bailey is definitely the only specialist for the wing, but Wenger rarely plays wing specialists on the wing.
I'd expect Mkhi to get minutes on the wing and I could see him playing PEA and Laca on the wing with one of them at CF, but that only applies if we are playing 433.
With a 343 Özil takes up one of the wing spots too.
One of the best things about the PEA and Mkhi signings is that it will allow us to change formations and rotate players. Unfortunately, these are two things that Wenger has never been good at.
PEA and Laca would make a great forward pairing and we could have a diamond midfield with Özil, Ramsey, Wilshere, and Xhaka.
I think Bailey is good enough to start for us, but if we want to be a top team, and top teams rotate players and change formations, then he definitely can't be an "automatic" starter.
Out of this potential front six, PEA, Laca, Mkhi, Özil, Bailey, Ramsey, Wilshere, and Xhaka are good enough to start every match, but at least two of them will need to be on the bench.
