When we brought Glasner in he had been out of work since the end of the preceding season, and was happy to remain that way until the following summer when he was originally due to arrive with us. In other words, he was willing to be out of work and wait to see what came up. Even if he doesn't have any options he likes right now, I imagine he will just chill out for a bit and wait. It's never long before managerial vacancies come up.
I'm sure most managers would prefer to go in during the summer and have the preseason, but Glasner showed that he could arrive midseason and have an impact with us. In may ways that makes him more attractive to clubs I should think. Some club or other will be in 'crisis/meltdown' because they have lost a few games. Their manager will be under pressure. The fans will grumble. Social media will exacerbate it. The owners will panic. Meanwhile, Glasner will be out there, free of obligations, available to start immediately without costing any compensation.
It might even increase his chances of getting something good.
