"Let's not waste Messis best years" seems to have died a little.
No wonder Messi loves Valverde as he has proved that he doesn't waste his best year on a developmental project with kids and the Cruyff way[SUP]TM[/SUP] and no trophies in the end, but gives him the titles he deserve. Valverdes project is to depend on Messi, give him clean sheets and a great defence and leave it to him and his BFF to score. As they always scores and decides the games it is a great plan. More secure to get trophies that way (at least in the last 2 years it has been) than score 5 when opponent regularly scores 3-4 against you, imo.
When Messis CL-thirst is satisfied for now with one this year, and competing next year with a better squad, then we can begin to have this "CL is a bonus" mentality again, which could help to win it even more, as we have seen with Real. That is what I dream of/hope for, anyway.
I'm open to the possibility that the arrival of e.g. Griezmann could help us get so many goals that we could slack a bit in defence to score more goals. But until we have won this CL and maybe 1 other the most secure way, I'm ready to wait for that.
