Olympique de Marseille coach Jose Anigo has stressed that Florian Thauvin will need time to fulfil his potential after the winger came in for criticism in recent weeks.
The 21-year-old moved to the Stade Velodrome from Lille at the start of the 2013-14 campaign and impressed with a string of fine performances early on.
However, Thauvin has been struggling to find his best form since the winter break and has been criticised for his relatively poor showings.
"There is no problem with Florian," Anigo told L'Equipe when questioned about the attacking midfielder's form.
"Simply, he is having a bad time right now. But remember he did not have pre-season preparation for the reasons we know and today he pays for it.
"He is only 21, we must give him time to grow slowly."
Thauvin has scored six league goals for Marseille in 22 appearances.
OM currently sit fifth in the Ligue 1 table with 43 points from 27 games.
