To be fair, If you watch back the city goal it’s actually hard to find a shot of him getting back, it’s pathetically slow, you see him basically walking into shot at the last second if you rewatch them on YouTube with the classic TV view, Either way, Grealish was being picked up by someone covering for Dalot. So the least he could have done was sprint back in to help his teammate out or pick up the spare man (Bernardo).
I don’t just wanna hammer our players constantly but the basics and the bare minimum is, if you run forward, you’ve gotta get back even quicker.
Garnacho is another one who’s clever at acting ‘busy’, it’s easy to see through when you know what they are doing.
Similar to how McTominay was a phenomenal hider away from home against the top 6.
