Wow. Quiet a change of tone from his predecessor. When Roberto first came so many embraced the new positive and ambitious spin. When the reality of decline set in perceptions changed.
RK's Moyes like lowering of expectations is now seen as refreshingly honest. How long that lasts depends on the results.
I don't think he's lowering expectations, he only accepts the best. That is clear from his anger of the players not being fit and not having transfers done quicker but he also understands the transition was made difficult this summer.
Koeman is a winner by any means. In his first season at a club he qualifies for Europe or he wins a trophy. I'm sure he wants that to continue here.
