French agent David Venditelli has questioned Toulouse defender Jean-Clair Tobido's move to Barcelona.
The teen will move to Barca when his TFC deal expires this summer.
But Venditelli, who has been the agent of Chelsea defender Kurt Zouma, told France Football: "There is a sporting risk, because the playing time will be reduced, even if the recent example of (Matteo) Guendouzi at Arsenal shows that it can work.
"Zouma, I would rather have advised a less elevated orientation, a good compromise like Inter Milan. But we must also understand that when Chelsea or Barça comes knocking on the door, it is very complicated for a player to say no..."
Zouma is this season on-loan with Everton.
