I've said for a while that Emery's track record suggests that any striker would likely excel under him in a way they hadn't before or after.
His successes at Valencia / Sevilla / Villarreal/ us, have all been built on the back of turning a solid, journeyman striker (in the case of the middle two clubs, more than one) into something that they never did again without Emery.
As a result, when we do end up chucking £40m+ at the eventual Watkins replacement, I'm going to be pretty excited to see the result, regardless of what they'd done in their career beforehand.
That said, Strand Larsen would definitely be at the lower end of the nipples-tingling scale.
