Even if he’d come out of isolation earlier this week, completed and signed the contract, been registered and had a chance to train with the team for 4 or 5 days; he still was never going to be starting for us tomorrow.
No matter how good a CB he is, putting a completely new stranger into the back line, with little time to get to know his team mates, or form any sort of working partnership with the goalie and fellow defender’s, would have been a recipe for total calamity.
Even if he signs later today and trains with the squad from Monday morning, it’s still a risk putting him in the squad for the 2nd fixture.
