Let Jonathan Bamba's interlocutor be reassured: LOSC is present at the start of the season.
Like his winger, totally recovered after a disappointing last season, the Mastiffs bite vigorously in all the oppositions offered.

The only unbeaten team in the championship with Rennes, Lille has two points ahead of PSG and the Bretons.
All the lights are green before starting a new European campaign this Thursday against Slavia Prague in the Europa League.
