"Blanc does everything well, nothing poorly and nothing great, but you get the chemistry" - that's my summary after playing around 50+ games with Blanc.
This guy is huge, he's tall and can hit a lot of headers, but he doesn't have a lot of accuracy there - I think I did only one goal header actually. But defending in the sky, this guy is the master. He will win all header in defense! so, if you have short CMs and you need that extra tall guy helping in the sky defense, he's perfect for that. He's fast, but not strong, so depending on what you want to do with him might change drastically the chem style you'll use. His work rate makes him do better at defense, but he's stats are more suited for attacking I would say, since physical is not great, but dribbling, passing and pace are good. Long shots too, all good (but not great).
I bought him because I wanted a complete CDM, a guy that rule the mid field and stop strikers on getting near the box, but at the same time agile and accurate enough to do great passes in offense and shoot or take a header once in a while. He kind of fit perfect there, more in the CDM part, BUT, he's slow and he's strength and aggression are low as well - so I decided to go with Anchor chem on him, and then he started shining as CDM, he's height and his long legs help him to tackle and intercept attacker easily - I guess if you add a Hawk/Engine/Hunter/Catalyst could be use as CM/CAM and be VERY effective at attacking as well, but remember he'll try to come back to help on defense rather than attacking because of his work rates, so this is not the the typical end-to-end mid fielder that you might be looking for, such as a Vidal, Petit, etc.
After a while, I decided to change him with Kante, I didn't needed the extra chemistry links that I was getting from him and Kante is faster and stronger (better CDM specifically for sure), and WAY more cheap - so now I'm looking to use the coins to invest and get something better in the offense.
If you don't have any crack Icon CM, such as Petit, Vieria or Rijkaard - then this is the cheapest and best bet to work chem links and get a hell good CM.
Dribbling - not crazy, but awesome for a huge guy
Defensive Heading and LOOOONG LEGS (don't get fooled by that 79 standing tackles, this guys fills like a 99 there!)
Stamina - at 70" this guys will feel way slower
Weak - needs chem to bully other players
Work rate if you want to use him as CM/CAM, if you want him as CDM, then you have the weakness problem
