Champions Montpellier moved into the top half of the Ligue 1 table for the first time this season as they secured a third consecutive win at home to Bastia.
After Marco Estrada's sensational 14th-minute opener, second-half goals from Emanuel Herrera, Younes Belhanda and Anthony Mounier ensured the recent resurgence of Rene Girard's side has now started to gather real momentum.
The 4-0 scoreline was Montpellier's biggest win of the season - beating the 3-0 success over Ajaccio only last weekend - as their disastrous start has started to fade from memory.
