Arsenal fended off interest from Barcelona for their captain last summer, but it proved to be a campaign of frustration for club and player as the Gunners came up short in their quest for silverware and Fabregas spent lengthy spells in the treatment room.
Talk of a summer move to Barca has been quiet in recent weeks and Wenger is convinced his captain is fully committed to helping Arsenal fulfil their potential.
"I expect him to be here," Wenger said. "I will fight very hard to keep him here. You have always to fight when you have a player of that quality.
"I believe the biggest pride for a captain is to be committed to his club and deliver trophies to his team.
"A player who changes every time when he is frustrated that he does not win a trophy goes nowhere. I believe the quality of a sports life is to be committed to his club and not just move on when it does not go as well as you expected it.
"I believe that Cesc Fabregas played 22 games this season out of 38. We expect him next season to play between 30 and 38 and that will make a huge difference to our efficiency as well."
