The Poch quote was as much about the players age and coming from a different league. Ndombele only had a couple of seasons in the French league so still lots of room for development.
“Still for me, when you sign a player, despite the amount you pay, with the profile of Tanguy Ndombele or Giovani Lo Celso or Ryan Sessegnon you need minimum one year and a half, or two years.
Look at what happened with Son or Sissoko, they started to perform in year two, year three. That is why when you are so young, today the market is the market, you cannot judge the player because you paid some kind of amount.”
