Your comparison is flawed. O'Neil and Slot are completely different situations, and you can't claim Slot did nothing wrong. The club's needs now are not the same as when Slot was appointed. Obviously, there was little evidence that he could solve the team's issues.
Let me tell you what’s happening.
Bournemouth owner, Bill Foley once said that he had to sack Gary O’Neil who had done a fantastic job to keep them up, so they can appoint Iraola.
O’Neil did not do anything wrong, but the owners had a vision on how they wanted to play, and Iraola fit that description. In fact, he said they’ve been monitoring Iraola and luckily for them, Iraola became available.
So, they had to sack Gary O’Neil asap so they could appoint Iraola.
It’s the same pragmatism that is in play here. Liverpool owners, FSG, are seeing that Iraola is only available for now, so it’s either they sack Slot asap or miss getting Iraola, who is the most sought after guy at the moment.
Coincidentally, Iraola plays a high press and quick transition style, something Liverpool are known for under Klopp and Slot’s league-winning season.
I’m sure Iraola will fancy this.
