I think this question depends on how much you believe in players they have brought in this summer and how much they can get out of some of the older players they also have.
If you think that some combo of Gravenberch, Mac Allister, Szboszlai are fixing the midfield, then sure. If you think Nunez is on the ascent, and that you can get something out of Diaz, Jota and company, then sure.
Can Salah / Virgil continue to produce at their elite level?
I think there's also some young players who have a lot of upside (Quansah, Elliott, Jones, Bradley and a few others) but depends on a lot of things going right, or who comes in. Some of it will also certainly be down to the coach they get. Some players will be gone.
