I think it also suggests that Joao Felix and Jonathan David might suit the football Ten Hag wants us to play here better than Osimhen. We seem to look to win the ball high up the pitch and play a lot of passes to feet to players on the half turn and link up with quick short passes, and those first 2 guys are well suited to that, as is Martial.
Osimhen might struggle playing against a deep line, apart from being an aerial threat, but we're not exactly hitting a ton of great crosses for Cristiano, who should still be looking an aerial threat with his timing and leap, even as the rest of his game drops off a cliff, since he can obviously still attack a ball in the air well.
Rashford's pace isn't doing a ton for us as a striker up top. I think we need a striker with a very good first touch who can play in crowded areas because Ten Hag's football so far looks most comfortable when Lisandro has it at the half way line or Antony has it on the right and then we look to link some quick short passes to combine and move the ball vertically quickly without everyone getting out of position or our fullbacks overlapping. A 9 who can turn with the ball and play a good one touch pass with his back to goal seems like the style that will work here best, so far.
From what I've seen Martinez is up to it, though I find he's either on or off whenever I've seen him, rarely just good. Kane would definitely be too, but I don't really see it happening. My guess is he takes a pay cut and ends up at Bayern.
