Top european schools emphasize on laguage requirements.
INSEAD - atleast 3 languages (english, french and additional)
IESE - English and Spanish
LBS - 2 foreign languages.
Rather LBS gives an opportuinity to learn different forgn language, but it not a must. IESE, on the other hand is a complete bi-lingual program. Spanish being the only forgn language taught.
I hope this helped.
