Since returning from injury the Spaniard has been playing in an advanced role, with Wenger employing a 4-2-3-1 system. However, with Arsenal struggling at Wigan Athletic on Saturday and with Fabregas being man-marked by Ben Watson, he was moved back and came into his own as the Gunners returned from 1-0 down to win 4-1.
"We dropped Cesc deeper into midfield and pushed Theo Walcott upfront," Wenger told the club's official website. "I felt that we needed a bit more creativity.
"At some stage when a guy is man-to-man marked you either push him completely upfront to create space for other players or you push him completely deep. When he's in the mid-zone and the ball comes out it becomes very difficult.
"It is a very difficult question to answer about whether that is Cesc's best position or not.
"He certainly likes to be at the start of things but then he can also give the final ball.
"I would still say the deeper role suits him more because he likes to get the ball from the centre back and he has a good long pass. That's more him than a guy who plays behind the strikers who might have more pace to penetrate.
"He is very good in the hole too but I believe that is because of the quality of his passing and less for his individual game."
Fabregas will again captain the side as Arsenal host Villarreal in the Champions League quarter-final second leg on Wednesday looking to build on the 1-1 draw secured in Spain last week.
