If Robinson does go, it makes absolute sense to promote from within.
Unless you're a club who can pay top dollar for a new manager, and also pay to bring in the players he wants for the system he wants to play, then it's the best option. Lasley knows exactly how we've been operating of late. He knows the systems that are working, he knows the players we have, he knows the youth players earmarked for a step-up, and he knows the transfer targets we have.
It's seamless, and also cost-effective.
