Yeah he isn't ready for the Ligue 1 yet. He is too static, Giroud were moving much more to help his team to build offensive actions. I still don't understand why Charbonnier isn't on the starting XI, he will help much more his team to play like last year. Charbonnier come back a lot, physically he is very strong and he has a good technique for a player of his height.
Herrera was already a ghost during the last games against Lyon on "trophée des champions". We should be patient with him as it was one of the best defense in Ligue 1 (Toulouse), but Herrera need a lot of time to understand how escape to French defense.
