You can see why they sacked Koeman, but I'm not sure it was the right decision. Koeman will be laughing. Doesn't have to pick up the players and find form and gets x million pay off.
They bought really poorly over the summer. How much on Siggerson alone? Then with that many players coming in you need to give a manager 6 months to let them settle and find their way of playing together.
They should have bought players with a system in mind, not just stock up on similar ones, but with a clueless manager it would never come together. He kept picking unbalanced sides and they continued to play poorly.
