I actually think this a good move by Everton, thought it would have been ****ing stupid to give him a 3 year contract but a loan move could turn out very wise imo.
If you think he's still that capable of taking points off your rivals, why are you getting rid of him?
That said, I still reckon he could do a job at clubs like LCFC. I'm not so confident he improves Everton, though.
Okazaki's a very useful player and he does a lot of work that's not really appreciated. Vardy gets the goals and plaudits, but a fair bit of that is down to the graft of the player next to him. Very useful option and quite different to what Ollua or Slimani offered.
