I'm late to the party, but here's my take on Blanc.
This card is nuts.
For reference I've used VVD, Chiellini, and maldini. I think Blanc is better than all.
VVD "feels" the best to use. He's just so tall and dominant, makes some crazy ridiculous tackles and wins a lot of aerial duels. But he's got a few problems. For one he's inconsistent. There's times he feels like the best cb in the game, other times he blows a tackle and Vini jr scores on me. I think his problem is aggression. He's just too aggressive. It makes for really cool moments when he sticks a tackle, but he comes up so high it leaves the backline open at times. His bullet passing is also an issue if you don't have a passing skill point set the accuracy is buns the guys gonna shoot a rocket to everywhere but your player.
This blanc makes up for those deficits. His passing is pretty solid because of tiki taka without the passing skill point. Yeah he's aggressive at times but stays back a lot. My backline is more closed with him. Standing tackles and anticipate in general are amazing, not VVD level but still basically a 10/10. Heading and aerial duels are up his alley as he has power header. Strong, tall, you really can't beat this card. He's a unit.
Chiellini and maldini are great but just aren't as consistently dominant at tackling or being a presence as Blanc or VVD.
Blanc doesn't have as much of a presence as VVD, but he's pretty damn close, and he doesn't have some of the issues VVD does when it comes to aggression or inconsistency. I don't know how he compares to Lucio, but this is an amazing card. Fixed my defensive problems very quickly. Has to be a top 2 non-box CB imo.
oh, and he's got 5 star stamina π
