I've made this point many times in the past, about how we don't sign players with high potential but wait for them to develop at lesser teams and then end up paying a premium for the finished article. People are always frustrated that we pay top money for those guys but the counter-argument is that they wouldn't get that development time with us, and wouldn't become the players they are capable of being.
That's where Harvey is. He's the proof of that argument, the guy with massive potential and ability, who isn't afforded the game time to develop. The rare exception of a player who we've actually signed and kept around the edges of our first XI. But to get that time in our team, you have to be exceptional (e.g. Trent - don't be blind-sided by the last few years, he was off the scale as a kid), and Harvey's not exceptional. He's very good, and he could perhaps become exceptional, but right now he's not there.
I'll be gutted to see him go and will wish him all the best, but it's more in his best interests than ours that he moves on and grabs the opportunity to become the player he can be. If he stays here too much longer he might never reach his potential. Some mid-table team is going to get a cracking player, and I hope he'll do well with them, but I hate to see a fan having to move on.
I think he was getting enough time, and would have got more, under Klopp.
The more alarming example for slot is Quansah, but he's not an attacking player so no one gives a shit.
