The Whites midfielder has suggested his teammates want Evans in charge next season.
Evans' position has been shrouded in doubt since day one and a report in the Mail last month suggested an extension on his short-term contract will not be forthcoming.
The report claimed that Whites' players had lost faith in the 53-year-old, who has since delivered three successive victories to move his side to 11th in the Championship.
January signing Diagouraga was on target in two of those and appears to be enjoying his football under Evans.
When asked about the Scot's future at Elland Road, Diagouraga told the Yorkshire Evening Post: "You can’t help speculation.
"All we can do is go out to work and put in a good shift for him and try and win as many as we can.
"Everyone is happy and everyone can’t wait to play another game, everyone is looking forward to another game. Since I have been here it has always been unified here but sometimes you get the rub of the green and sometimes you don’t."
Earlier this month, Evans claimed that other clubs were interested in his services should he not be kept on at Leeds.
The bookmakers have him at 9/2 for the vacant Nottingham Forest position, while the Glaswegian's boyhood club Celtic were linked by this website on Wednesday after Ronny Deila announced his decision to leave his post at the end of the campaign.
