My worry with cutting Bruce loose is finding a manager who plays a certain style while handling the pressure.
I always firmly believed a major problem with some of our previous managers was one of expectation. Villa still hold a certain status and expectation. One McLeish, Lambert, Sherwood and Garde struggled with. Other than a small stint at Spurs, all those managers arguably came from teams with lower expectation and status.
I thought Bruce would be different. He's managed at all levels and while he will openly admit we are his biggest team, he should have enough experience in management to cope with pressure and expectation.
Defensive tactics, style and 'losing sleep thinking about losing' show he isn't coping well at all with expectation. I honestly believe if he took our exact squad with him and went to manage someone like Brentford, he would be storming it. He's scared to lose. He's scared to mess up this big chance and whether he even realises it or not, it's impacting him.
So the next guy needs a particular skill the others lacked. The ability to play good football, and not be scared of our name, badge or expectation. I don't know who that is, and it's not for this thread, but it's a big ask.
Thankfully our need to part ways with Bruce (in my opinion) outweighs the possible risks and worries.
