The former Montpellier striker completed his move to the Gunners yesterday.
"Arsenal is a great club, the facilities are wonderful, but I feel it is a club that takes big care before signing a player, notably considering human values.
"There are French players. There is also Arsene Wenger who let me understand he really wanted me.
"Chelsea is very nice, it is a great club, but I am not convinced Di Matteo knows who I am."
