It's an interesting challenge isn't it? Parish can look back and conclude that under Glasner the club hit new unprecedented heights, now does he consolidate or push further? Of course it all depends on funds. Naturally the new incumbent will be aware of what has gone on before and the state of current play. With a clean slate, the loss of Guehi, and limited funds, a new manager would likely find matching or besting Glasner's record a challenge. I find it likely that the best that could be hoped for would be mid-table respectability. I say this based on our current squad, transfer history, and funds available.
