Because we’re not going anywhere this season, the couple of points we gain from his late super sub goals don’t mean anything, and insofar as he’s robbed important minutes from Nketiah and been pretty useless in Europa he’s been of negative value there. He’s 31 and the 30m, plus just as importantly the wages off the books, we could potentially get from a desperate Everton would be of exponentially more value than whatever value he provide an us, which is rather little. Pretty simple really.
And thinking that he will do any better than Lacazette we a starter is so naive honestly. Just look at his Europa League performances or remember how it was with him before Wenger finally figured it out the right role for him.
