It'll be massive in terms of the way we play, because so much of what we do goes down our right to naturally exploit his passing range and ultimately getting the ball to Salah. But it may be a good think to spread our attack around. We've lost bigger and better players than Alexander-Arnold, as has everyone else (I remember being convinced you were buggered when Henry left; you weren't) so we will ultimately get over it. Bradley is a phenomenal talent, but a different player. It may not be awful if we played in a more balanced way (he gets into the box more and will get up and down the touch much more whereas TAA naturally pings balls, often wastefully, but when it does come off it's extraordinary)
The local "knowledge" has always been that TAA would go, and that Van Dijk and Salah would stay, this is at the start of the season. Even that has slipped recently, no one is sure anymore. That's then not then one hole to fill, it's 3 huge ones
And naturally gaps I can't see how we recover from quickly.
For instance, we are constantly linked with Isak. The only way I see us being able to afford Isak is if Salah leaves. Equally, does Isak join if someone like Salah goes; what is he walking into? All made up rumours of course but one can't ignore where we are with possibly the greatest single player season in PL history in the offing.
Edit: I still think both will end up staying. We obviously won't get Isak. Trent will go and we'll replace him with Bradley and Quansah as backup. We still have gaps to fill.
