Olympique Marseille have two permanent options in the loan deal of Eric Bailly.
The Manchester United defender is on a season-long loan with OM.
Bailly told La Provence: "I don't think about that option.
"I am fully involved in OM, I want to play as many matches as possible and, why not, win trophies."
L'Equipe says the purchase option is estimated at €10m and will be automatically activated on two conditions. The first is when OM qualify for the Champions League and the second is when Bailly plays 50 per cent of the matches this season.
