I agee 100%. I prefer Messi playing from the right, cutting inside on his left. But that's not happening, at least not in minor liga matches.
I think we're doing fine as it is for La Liga. Some crappy games here and there, but manageable under the context of our rivals not being all that good. We can afford to basically let Messi do his thing, as long as we know this type of stuff ain't gonna work vs top class teams. It's way too loose.
Games in CL are too close to command them the way we do in La Liga, and barely see brilliant no10 playmaking in these few years once you get past a certain point. It's mostly fast, high octane football with a lot of intensity. Pretty physical stuff, with a high emphasis for counter attacks and fast transitions. Put Messi on the RW mosty, and Dembele on the left, with Suarez in the center occupying two CBs and you'll have real guns who can hurt teams. And if we pack enough energy and aggressiveness in our midfield, I think we could go far this year.
But if we fool around with Messi the mage wondering around everywhere trying to apply his genius stamp on every play we ain't doing anything, no matter how great Messi is. The channels will be blocked 90% faster than they are vs a standard La Liga team.
