Im incredibly optimistic. Great teams in any sport, and great businesses are all run by having the right people in charge. Its not even about who the owner is, but that the owner understands, as one put it "the importance of hiring people smarter than you". Its about those that lead the organization right below the owner. If the right ones are brought in, while it takes time, often years to see full results, those results can last for a decade or two. The two most important pieces to a club are its manager and who finds and negotiates for players. I believe we finally have the two best ones we have had in a long time here, so Im very optimistic about the future.
Im not naive enough to think Don Carlo can get us in a champions league spot, but I do think he can get us into Europe this season, and after the summer transfer window set the team up to legitimately compete for 4th for the first time in a long time.
