Tunisia defender Aymen Abdennour has joined Monaco from Ligue 1 rivals Toulouse on loan until the end of the season.
Abdennour, 24, signed at the end of the January transfer window, along with Bulgarian striker Dimitar Berbatov, who moved on loan from Fulham.
"I am proud, Monaco is a big club," Abbdenour told the club's website.
"[It is] very professional with a great technical staff, high quality players and big ambition.
"I'm ready to help my new team-mates. I will do everything I can to succeed. We have a fantastic goal."
Abdennour, who has 30 caps for the Carthage Eagles, has signed initially on loan, with an option to turn the deal into a permanent four-year deal in the summer.
"Aymen Abdennour is a very solid defender with a profile that we didn't have in the squad," Monaco vice-president Vadim Vasilyev said.
"We have been following him for a long time and so we are very satisfied to have reached a deal with Toulouse to bring him to Monaco."
