Simply put. The best striker we have had at Everton since Lineker.
Take him away, and we become a very average team at best. Its VITALLY important for the immediate future and success of this football club to hold onto him. If we show continued improvement, desire, ambition in the Moshiri/Koeman era, break into the CL spaces (this season a VERY longshot, next season a big possibility), beef up the squad with pure quality in the summer - we have a chance of keeping hold of him.
Lose him - the only silver lining would be that we can get astronomical money for him (If he finishes the season as the PL top scorer, we could get between 60-70 million for him) - then its imperative we look to add 2-3 really quality strikers, if they can be persuaded to come.
Do I want us to lose him? Even for that amount of money? Categorically, no. I live in the US. All major sports here have an award at the end of each season, its called the MVP award. Its supposed to be awarded to the most VALUABLE player - meaning which player is indispensable to his team. You all know where I'm going with this!
I love him. He has every right to be discussed in sentences with Dixie Dean, Bob Latchford, Graeme Sharp, Andy Gray, Joe Royle, Gary Lineker etc.
