Meslier completed a move to Leeds United on Thursday.
Leeds United could sign Illan Meslier on a permanent basis next summer.
Leeds confirmed Meslier's arrival on a season-long loan this morning, but failed to mention any additional clauses.
And according to the goalkeeper's parent club, Lorient, the Whites do have an option to turn his move into a permanent one.
The French side made the announcement on their official website, before wishing their academy product an "excellent season" in English football.
Meslier is expected to compete with Kiko Casilla at Leeds, and could be rivalled by Kamil Miazek, Will Huffer or Harrison Male below him.
The 19-year-old Frenchman replaces Bailey Peacock-Farrell, who left to join Burnley at the start of this month.
He played 28 times in the French second tier last season, his first at senior level.
It is unclear how much Leeds would have to pay for Meslier, who has three years left on his Lorient contract and a Transfermarkt valuation of €5 million (around £4.6m).
