No, what you're forgetting is our 'team in transition' situation. As soon as we make a little progress you want us to jump straight into European competition, even thought we have barely established ourselves in the PL top echelons.
We have been here before under Moyes and Martinez and saw what happened. I dont want that again. I want a really solid base first and squad that is ready to compete on all fronts.
And Sevilla is the kind of tough team we would be up against and I really dont think we are ready. Yet.
You can't decide to live in some arbitrary stage in the future when circumstances look rosier. Koeman stated the target this season was 7th and hopefully a place in Europe and we look on track to achieve that. Next season it might be a trophy and we'd be in four competitions to have a good crack at that.
Most teams could lay a claim to being 'in transition' of some description. Chelsea, Man U and Man City could this season but you won't hear those fans complaining of over-achieving.
Arsenal will probably fit that description next season. Our leading goalscorer might decide he's off if a big money bid comes in in the summer leaving us having to rebuild. Our manager might depart to sunnier climes if Barca decide to ask him to interview....
You've just got to try and over-achieve in the present, make contingency plans for different eventualities and the future takes care of itself.
