There's some managers that are good, they can thrive in 38 fixtures trophies because they're pragmatical, but it doesn't mean they have what's needed to push when they need to in the important dates.
Valverde reminds me of Emery, they're good in the tactical sense, can manage a dressing room better than 90% of the coaches out there and as long as they have a good squad, they can milk some titles from it.
But they're not winners, when push comes to shove they falter, Emery showed that time and time again with Valencia and PSG, Valverde had the same problem with Espanyol and Athletic, and the leg vs Roma last year was another nail on his future coffin with us. With some coaches a team can lose, but most players look good with the effort done, when a team led by someone like Valverde loses you can see frustration in the players, they know they're being held back like underdogs.

A guy that can piss off Iniesta and "convinces" one of the most successful rosters of all time to defend a 4-1 vs Roma is not the kind of manager you want for a Barcelona, Real Madrid or United.
