You think Lukaku will stay here finishing midtable because he likes playing for Martinez. 1st chance he gets he'll be at a Champions League club. That could have been us this season if we had a competent manager
No. But he might stay another season or two and wait to go to a REALLY big club, and not jump at the first CL offer (he could do that this summer easily, and would likely do so if we changed managers).
In the scenario where we spend the Stones money on a LW and top keeper (in my view, a better use of funds when we have Funes Mori and Galloway available and Stones wants to move on), I could see Lukaku being content to stay here, yes.
Has this season raised his visibility and value, even with us mid-table? Certainly. The partnership with Deulofeu plays a key role. If we keep giving him the RIGHT support like that, and we put in place a real plan to make a Top 4 run, he could stay. Accomplishing that, and playing well in the CL with Everton, could set him up for an elite club move. THAT is what he really wants, and to be happy until the perfect opportunity arises. I don't think he's interested in another "stepping stone" as long as he feels supported and happy.
