What do you think of them as a pairing + would you sell one in summer or both...or keep them?
I would keep both of them IF:
1) we were able to sell some of the other short contract guys (Mina, for instance) and overpaid wasters (Keane, Gomes for instance). As much as it will help us to have the likes of Delph, Sigurdsson and Tosun falling off the payroll, OOC departures don't generate any income... And we need income.
2) we are able to extend Richarlison's contract. No point keeping him this summer only to sell him for £20m next summer.
If we can't achieve BOTH of those things, I would reluctantly sell Richarlison. Preferably overseas, to a club where he can win trophies. Kind of like the Gana-to-PSG deal: no hard feelings, thanks for your commitment here, good luck at your next club.
I like the flexibility Richarlison provides. CF, wide left in a front 3, second striker / 10, wide left in a 4231... Goal threat in any of those positions. These are reasons to keep him but also reasons why he should command a hefty fee.
Having him available to share the load out on the left means we can get the most out of him and Gray, and he's the only useful cover we have for DCL at the moment too.
Our issue is midfield. Sort the centre of midfield out and you'll get FAR more out of Richarlison and DCL. And Gray, Gordon and Townsend, for that matter.
