Similarly to Yamal, Cesc also came through the La Masia system at Barcelona before he made the move to Arsenal.
"I think he (Yamal) is a unique talent. He is the type of player that you just let go out on the field to play football," Cesc told ESPN.
"I think this is already a great player, a mature player. What I like most is that it feels like he's out on the street playing. It looks like everything is so easy for him."
Fàbregas stresses that he dislikes comparisons between players - but he understands that Yamal is being likened to Lionel Messi.
"I can understand that. I don't like it, because every player is different and everyone has their own story. Lamine needs to go his own way - but there are definitely things that make you think of what Leo used to be."
