Saint Domingo
Player Valuation: £90m
True, but we need a second, proven, goalscorer in the squad too. We need two players who can guarantee comfortably over 10 league goals a season. We know Lukaku will get close to 20, but can we get another striker in who'll get 15 plus?
Barkley (1 in 6 roughly) doesn't score as many as he should, and the same can be said for everybody else you mentioned too. Mirallas is a one-in-four player and Deulofeu will assist 5 times more than he'll score, which is fine for an out-and-out winger.
We desperately need another top striker, you saw how Lukaku went right off the boil (for whatever reasons..), and what happens if he gets injured? Can't rely on just one goalscorer.
I expect we'll get another striker (if Niasse really is not up to the standard) but I think we will see a far higher return from the players you've mentioned under a decent manager. Barkley when in form scores goals (like at the start of this season and his debut season). He and Mirallas could easily hit 10 or above. Deulofeu seems less of a goal scorer but his assist number is great and as he plays more regularly his decision making and finishing should improve.
I can see only good things from that attacking quartet in the future if they are managed well (presuming Koeman rates them and plays them)
