We definitely need the quality in depth. 3 top widemen for 2 positions is nothing in today's football. Even 4 is passable given the games.
What is obvious is that Raphi so far is showing he has a world class engine and also fits Flick style of play. But he will literally have a sell by date that we will have to time, and his output will dry up. Be it in half a season, a season or longer.
He won't be a lifer here basically, so we will need to know how will be the starter quality replacement sooner than later.
I believe the Saudi offer btw considering what they also offered for Vini. The wheels of public perception and interest has waned from that league and they will need to make another huge investment sooner than later.
From a branding perspective, they need to make the teams more relatable to western audience. There's only so many Weird Al Yankovic songs you can listen to before they all sound the same.
