I'm wondering in which game Arteta can afford to rotate players at all this season remaining? By that I mean players playing 80+ minutes every three days. Considering the toughness of the games coming up, including Luton who are a tough cookie.
Goalie? Nope
Been White? No
Kiwior? Maybe, with Zinchenko
Gabriel/Saliba? Nope to both
Rice? Nope
Jorgino? Yes, Partey
Odegard? Nope
Havertz? Nope
Martinelli? Nope. Watch them hamstrings lad
Saka? Nope. See above.
That's pretty much 90 minutes every game, every three days. Might risk Trossard but there's no easy game for them to step in more than 10 minutes.
Liverpool have easy EL games and Sheffield Utd, etc, to rest the likes of VvD, Konate, Bradley (TAA), Gomez, Salah, Nunez (Jota), Diaz, etc. This is the big picture.
