It would be crazy if Gerrard was approached but if he really wanted to come and prove a point at a PL team, Everton would be perfect in so many ways.
He would upset a lot of Liverpool fans by coming to Everton too, so it is a risky move for him. I think it would end any chance of him coaching Liverpool.
He seems the type not to want a job just because of who he was as a player. I think he could be a target for Spurs for the same reason (if Poch does not work out).
In all honesty if I was Stevie Me I'd be wanting to test myself in the Champions League as the next step. He'll need to get into the group stage with Rangers though, but even then if they drop into Europa the next aim would be getting to a major euro final. If he came here it'd take too many years to achieve those aims, which he could do next season.
For him to be considered as Herr shiny teeths replacement, he'll need to be managing games on the biggest stage.
Long story short, he ain't coming here, and we wouldn't have him.
