Kylian Mbappe scored 26 goals in all competitions last season as Monaco beat PSG to the Ligue 1 title while also reaching the Champions League semi-finals.
Mbappe’s form has all the big club’s interested, with Real Madrid reportedly opening talks, but Abidal, currently an ambassador for former club Barcelona, says the figures being quoted are far too high.
"Mbappe is a good player, but his price is not £120m," Abidal told Cadena Ser. "I still think he wants to stay in Monaco and confirm his level there.
"He has to make a decision also thinking about his game minutes, because this is the year of the World Cup.
"When you start to pay £100m as was done by Pogba, then for a player with more talent you have to reach £200m and that does not represent the value of the players. Here at Barca, what price would be paid for Messi or Neymar?"
Abidal also gave his verdict on another exciting, young French forward Ousmane Dembélé. The 20-year-old Borussia Dortmund star scored the winner, assisted by Mbappe, in the recent international friendly against England.
"Dembele is a very talented player, he would fit very well in the club," Abidal added of a player who has been linked with Barcelona. "If the bench is strong things are achieved, the signings will help a lot."
