The player says he wants to add some of the Welshman's mental and physical attributes to his game but acknowledges he is still way off the Real Madrid star's standard.
Sessegnon told Sky Sports: "I think [the comparisons are] definitely a confident boost. [Bale] was one of the players that I looked up to when I was younger, especially when he was at Southampton bombing up on the wing.
"He has attributes that I want to add to my game. In terms of attacking intent, the mentality to get in behind on the left flank and dribble with the ball, I'm trying to add a little bit of that into my game.
"If I could ever become as great as he has become it would be a massive achievement. I'm so far off at the moment.
"I set my standards very high, so I've got a lot of improvement to do, I'm still learning the game."
