Monaco's teenage sensation Kylian Mbappe has been warned about the perils of moving abroad at a young age by former France international Youri Djorkaeff.
The 1998 World Cup winner cited the example of compatriot Anthony Martial, whose career has stagnated somewhat since swapping the Stade Louis II for Old Trafford in 2015.
Martial became the world's most expensive teenager when the Red Devils completed a £36 million deal for the former Lyon youngster in September 2015, and initially hit the Premier League by storm.
He was United's top scorer in his debut season in the Premier League, but the subsequent emergence of Marcus Rashford and the signing of Zlatan Ibrahimovic has limited Martial's game time so far this term.
After scoring 11 goals in 31 appearances last time round, Martial has found the back of the net on three occasions in 16 games, albeit mostly from the left wing.
Mbappe, meanwhile, has become the new darling of French football after a series of scintillating performances for the Principality outfit, sparking widespread interest in the 18-year-old's signature.
Speaking to French newspaper Le Figaro, Djorkaeff has urged Mbappe to consider all his options before deciding on his next club.
"If I were the president of PSG, I would sign him, but I would not be the only one [in for him]," Djorkaeff said. "He has tremendous potential, but he must be in the right conditions.
"He astonishes everyone in his maturity of play and understanding. It is very rare for a youth to have an understanding of the game and what is happening. Normally, it comes with experience. He already has this facet.
"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."
