Decent post mate.
and yeah IF Lukaku goes and the sum of ourt business post him in a attacking sense adding Sandro and say Gray then we will be up the creek without a paddle unless Sandro hits the ground running and his development last season continues for example- which honestly we won't know until during the season
But thats the worst case scenario - and actually would be shocking if it was the case scenario given we appear to be trying to add real depth to the squad so far.
The other side is that IF we do sell Lukaku for close to a world record fee, then much like a few other clubs around the world have done (Athletico for starters for the past 10 years or so) we will be a very very attractive step for any ambitious striker,they will see what happened with Lukaku at this team - going from a reject who was loaned out to West Brom to a player who walks in for a massive fee to a top CL level team.
IF he does go my estaimate would be that we would add a proven experienced player in this league - the likes of a Giroud, Vardy type.
and we would add another younger striker with a massive potential to him, be that Dembele, Dolberg, Batshuayi, Iheanacho or another from the continent probably using about 45-50m to do both pieces of business, we'd then add another wide forward type (like mane was) be that Berardi or Balde etc for an additional part of the Lukaku funds - which i think we will add that type anyway btw)
So add proven goals with one signing, the massive potential offinding the next Lukaku with a proportion and to give us depth we've lacked for years there, and to add another pacey goal scorer who can play across the front three.
