We're 14 games in to year 2, way way too early to tell. Some might say we need to win now, we just won our group in Europa, we're playing our best football there. We did well in the league last year so we know we can, this year is more about Europe. Next year or year 4 can be about winning the treble, let's be realistic for now.
I think it's more the personnel than the tactics. Arsenal plays the same way, they do fine each year, but they have tons of creative midfielders and quality. We have pienaar, mcgeady, and Osman. We have the framework of a great team, stones, browning, garbutt, Coleman, Oviedo, McCarthy, besic, barkley, mirallas, lukaku, naisy. We just need to fill the gaps with better personnel and replace the aging Moyes personnel. I think as the team grows and new parts are added old ones subtracted and RM gets the team he wants playing and buying fully in to the system he coaches we will see more consistency. Till then there will be hiccups and disasters. I'm backing the man.
Give the gaffer some time to see his vision through, Rome wasn't built in a day. Neither was barca or arsenal or other tiki taka sides. Look at Dortmund, they have tons and tons of quality, sometimes good sides just have a bad year.
