Too early. Gravenberch has been playing brilliantly for a matter of weeks. Unless you are a LFC supporter, you have likely seen him perhaps 2-3 times. Our only ‘big game’ in the PL so far has been ManU, most neutrals will not have been particularly engaged by those matches. The CL games would probably have attracted a little more profile, but not enough to really cement a reputation.
Mazraoui is out requiring a procedure on his heart. I recall him having serious complications with myocarditis after contracting Covid while at Bayern and so this seemingly a consequence of that.
