Acun has kinda made a rod for his own back in firing Rosenior for the way they played, as clearly the team under Selles was definitely rougher to watch than under Rosenior.
That said, the squad we had under Rosenior was full of promising PL loanees, and a couple of gems of our own, many of whom then signed for other clubs for 8 figure sums. The squad Selles has had to work with is vastly inferior, especially after injuries.
Selles has done a tremendous job with a clearly limited squad, and firing him would be an even bigger mistake than firing Rosenior IMO. He deserves at least until the end of 2025 with a full pre-season and the likes of Belloumi and Millar back in the team to see how the football improves.
