Personally I see it as unrealistic to expect us to suddenly overhaul Barca & Real Madrid. It could happen, but imo that would be a bonus rather than an expectation.
If Pep had a full pre season & there were a couple of huge players available to bring in I could imagine it, but even then, it's such a big change for the whole team, I'm expecting a transitional period & I get the impression that's actually the plan.
I also think Pep is here for more than 3 years unless it goes tits up. I didn't before he arrived, I was pretty convinced it would be 3, but ti all points to more & I think this plan is to stabilise the club for the future as well as the short term trophy hunt.
I agree about Nolito btw. If you compare the highlights of his performances on youtube for example, to the best of Sané, he is absolutely miles ahead. People are dismissing him as a squad player & Sané as the 'star'. Nolito is currently way ahead of him.
