That disappoints me as well, but a useful of thinking about the upcoming season is that no matter we were to do there's no chance we're competing for a treble. We've lost a bit of pulling power as we've seen from Anderson going with City over United (though in his case I think we've dodged a bullet) and players who might have tempted in the past such as Tchouameni just aren't taking United seriously. We need something small before we can seriously compete for the cream of the crop. Going for depth makes sense in another sense -- putting in long runs in all four competitions as even if we come up just short in all four competitions, restores some of the pulling power that we used to have.
But beyond that, we may have next (post-prime) Casemiro with Tielemans, and if Rashford is to stay at OT I'm actually confident that he'll approach his prior form for us, which gives us flexibility at CF between Cunha and Sesko, and I expect Sesko to have a fantastic season for us.
My real concern right now is at both fullback positions. We all know about Shaw running on his last fumes, and between Dalot and Mazraoui we have two fullbacks who can do a job but neither of whom present a real threat in the final third.
