For all intents and purposes I think ETH has moved on from Amrabat to Onana, different profiles but maybe he values Onana's physicality over Amrabat's deeper build up skills which he knows Shaw and Martinez provide anyway. A Fellaini size with technique would be difficult for teams to handle and will be handy off the ball.
We must be prepared for Everton absolutely rinsing us, at least £60m. Maybe that explains our inclination towards selling youth players we would normally keep, we are fund raising for a big purchase.
