Nottingham Forest are currently in sixth place in the Championship table.
Karnaka recently suggested that Forest have ‘no limit’, such is the potential in their squad.
And Guedioura also does not believe that the Reds are playing anywhere near their peak yet.
Guedioura said: “We want to improve, it is not finished. The manager said that we have no limit and I agree; if we keep going like this, step by step, we will have a bigger and stronger team.”
Guedioura has played a key role in Forest’s team this season, but he has not featured in either of their last two matches.
Karanka’s side’s last outing came at Villa Park in midweek, and the match will be remembered for years.
Forest and Villa played out a remarkable 5-5 draw, which will surely go down as the most entertaining game of the Football League season.
Forest’s high scoring draw with Villa has left them in sixth place in the Championship table.
The Reds are next in action this weekend, when they are set to take on struggling Ipswich Town.
