Youri Djorkaeff believes Monaco star Kylian Mbappe should not follow in Anthony Martial's footsteps by moving to a big club early in his career.
Mbappe is one of the most wanted players in Europe after a phenomenal campaign while Martial, who also came through the ranks at Monaco, has struggled to replicate his performances of last season at Manchester United.
Djorkaeff told French newspaper Le Figaro: "He has tremendous potential, but he must be in the right conditions.
"Look at [Anthony] Martial, when you go to a big club, you have to adapt and discover something else. Mbappe must pay attention to all this."

Manchester United transfer target Tiemoue Bakayoko will reportedly only consider moving to Old Trafford if they qualify for the Champions League.
The Manchester Evening News quotes a source close to Bakayoko saying: "Tiemoue is listening to some clubs from England, including Manchester United, but there is nothing concrete right now.
"Manchester United is a big club and [Jose] Mourinho is a big coach, and Tiemoue needs a big coach to continue his progression.
"He wants to play in the Champions League and it will be a worry for a club that does not play in it. It will inevitably be taken into account."
