I get all this and I'd normally be alright saying "go on, let's give it another try" due to the horrific injury list. However, his inability to adapt and change tactics when faced with an injury crisis is horrendous management and inexcusable, he's sleepwalked all the way through the season, just hoping the continuation of the same tactics will eventually "click".
So what happens if we have a good Summer, but then Martinez, a new centre back and a CM gets injured in November, because we clearly don't have a manager who can adapt, it's like we need to be the luckiest side in the league and have no issues, then we might be alright.
