Think rationally.
He had a stinker last night
His form dipped last season to co-incide with senior players downing tools under the management of the worst boss in Everton's history relatively speaking.
He was our top scorer for 30 years.
He scores 20 goals + a season guarenteed.
We don't want a return to the 'Oh at least he works hard days' of Andy Johnson or James Beattie.
Basically we should be doing all we can to convince him to stay. Martinez ruined so many players (Stones, Barkley and Mirallas aren't getting a look in over in France as a result) and he got frustrated. We won't get any better than him no chance, definitely a case of better the devil you know.
How did Martinez "ruin" Lukaku?
Completely disagree with you - we can get a much, much better footballer than Lukaku. We won't get a better goalscorer.
I'd personally prefer the footballer. You can get goals from all over the team by being a better footballing team from back to front. As it stands now, if Lukaku doesn't perform (which is often the case), we don't score - and that's because everything falls apart in the final third when he's non-existent.
