Spot on.
The big problem was always going to be that it's all but impossible to replace Olise and Eze with anything like the same level of quality, and in the case of Pino and Johnson (so far, in both cases) the replacements have struggled. That doesn't mean the club haven't tried, or haven't spent money. I wouldn't be surprised if the next manager gets a tune out of at least one of them by changing the system to suit them. Look at Carrick and Man United yesterday.
Personally I'd give credit to the club for signing both Olise and Eze, when lots of other clubs would have been aware of their potential, and also for convincing both to sign new deals and stay with us, and then finally for getting good money for both. Along the way they were a joy to watch and in Ezes case, got the winner in a cup final. Brilliant business all round.
As someone else pointed out on here, the players that left didn't want to extend their contracts with us. They thought they had achieved all they could and wanted to try higher up. EXACTLY like Glasner. Yet he's moaning about them leaving!
What a disappointment. What a big baby.
