I would give it a 7.5 /10.
We have finished as high as the ability in the squad would allow. Considering the long term injuries to Bolasie, Coleman and Funes Mori that is no small achievement.
The manager certainly did not take the job to work with the squad that was already in place at Everton. January proved that.
RK is a manager that can get results and with better players in the squad we should be able to get even better results. He has given academy players their chance. However, we have seen that you can't just throw three or four young players into a team and get results. They must be introduced slowly and at the right time. A player like Davies is a bit of a freak and is the exception rather than the rule.
Next season...no idea yet as it all now comes down who we buy and who are sold.
Four or five really good players onto the current squad could see us challenge for the top four...we are probably only an extra two wins away from that this season...it is certainly attainable.
We need a quality goalkeeper, a centre half, a centre forward , cover at left back and I believe we need a more creative midfielder/striker(Rooney?).
This summer Kone will be leaving and I don't see Valencia being kept, I think Funes Mori will leave as well.
Coleman and Bolasie will miss half of next season and Besic still has to have a sustained injury free run.
It is amazing how the entire squad will have been reshaped in such a short time
