Wilshere has started four of Arsenal's five games this season and has impressed in midfield with the Gunners making an unbeaten start to the campaign.
The 18-year-old spent time on loan at Bolton last season and the first-team football has allowed him to blossom, something he hopes can continue to new levels.
Captain Fabregas also broke into the Arsenal side as a teenager and it is he who Wilshere aspires to be like as he continues to learn from 'the best.'
"For me, in the position he plays, Cesc is the best player in the world," Wilshere told The Sun.
"He is the perfect player for me to learn from because he is the player I most want to be like.
"I had to go out to Bolton last season because there are so many world-class players at Arsenal and I had to get some games.
"But I've come back to the Emirates stronger and more experienced and playing regular first-team football obviously makes it easier for me.
"Playing in the same side as guys like Fabregas, Andrey Arshavin and Alex Song has been the perfect opportunity for me to learn."
Wilshere, who earned his first senior England cap last month, believes Fabregas is not only a great player but a great leader, despite still only being 23-years-old.
"Cesc often takes me to one side and talks to me about my game. On the training pitch and during games, he tells me things to do and encourages me," revealed Wilshere.
"It is always easy to find him on the pitch because he makes space so well. He helps me through the games and is always talking to me.
"He's a great leader as well as a great player and obviously it would be nice to play with him at Arsenal for many more years and get more games together.
"He has told me I'm not going to play every week and I have to break through slowly and then, hopefully, get into the team more regularly.
"But I'm already playing in the Champions League at 18 and that's an experience some players of 33 never have in their entire career."
