The Blues got off to a steady start in the group stages with a home point, but Leboeuf was expecting the team to show its attacking quality in the game.
Sevilla were in control for large portions of the game, with Edouard Mendy having to pull off good saves to keep his team in the clash.
"I don't see what I want to see, I don't see the players speeding up the game and doing something, changing rhythm," the ex-Blues defender told ESPN FC.
"I saw Mendy is much better than Kepa. It's a clean sheet, especially after the first half, Sevilla had around 65 per cent possession of the ball away from home at Chelsea in the Champions League, that's completely abnormal.
"I'm pleased to see Thiago Silva because he's a talented player that brings something very special to the defence and makes it more solid, but after that, I don't see somebody in the midfield, especially offensively, somebody doing something special to create something.
"They're looking for each other, not knowing each other and we saw clearly nothing. The best chance was after an hour from [Sevilla's] Jordan from a corner kick because no Chelsea player was marking him and he had a fantastic volley, that's the only thing that I saw.
"Half a chance from Werner, another half a chance from Zouma, that's it, Champions League guys, Champions League. We want to see something soon."
