Manchester City star is positive ahead of this evening.
Manchester City slipped to defeat against Tottenham Hotspur last week and are looking to overturn their 1-0 deficit this evening.
A spot in the Champions League semi-finals against Ajax is on the line at The Etihad.
Manchester City may have lost the first leg, but defender John Stones is feeling confident.
Speaking at a press conference, reported by Goal, Stones said he and his City teammates have looked back at the footage of last week's defeat and have found reason to be encouraged.
Stones said: "From the last game we had our game plan and we stuck to that.
"After reviewing the game as a team we've found a lot of positives."
The £47.5 million signing added: "We can't concentrate on Harry and Dele not playing. What we've done best through the years I've been here is focus on us and do everything we possibly can as players to get that outcome we want."
Stones is hoping to be selected this evening in defence alongside Aymeric Laporte.
He did not elaborate on the 'positives' City spotted, deciding to keep them to himself and his teammates.
City missed a penalty against Tottenham and failed to score an away goal.
They cannot afford to concede any themselves, and Stones will have to be at his best to keep them out.
