Pep Guardiola believes Manchester City wingers Raheem Sterling and Leroy Sane will get even better next season.
The duo have been key players for City as they stormed to the Premier League title with a record 100-point total.
Both improved significantly on their overall tally of goals and assists from the previous season, with Sterling scoring 18 goals and Sane netting 10.
But City boss Guardiola told a Monday Night Football special: "They can do better. I have that feeling.
"If I didn't believe it I wouldn't say, but I think they can in simple things, the dribbling, first control, how you receive the ball and take decisions. It's training in smaller spaces and focusing on control, because that is the reality that is going to happen.
"What I learn from my old players in that position, they move in smaller spaces and the top, top players when they get two chances they score two goals, so they didn't miss. But the most important thing is they create a lot of chances for themselves and I feel the average can increase."
While Sane won the PFA Young Player of the Year award, Sterling finished the season as City's second-highest scorer.
And Guardiola added: "Raheem this season takes pleasure to score goals. Now he goes to the ball like a striker and scores a lot of goals. Last season we spoke with him and said try to get in the box in that moment, and I think he didn't feel it, but now he is scoring goals and going to the box more.
"Mikel Arteta [City assistant coach] has helped them both to make a lot of actions near to the box. The qualities one against one, we say to the wingers when you receive the ball, if the control is good, the shape is good, go, go, it doesn't matter if you lose the ball - try it.
"They work after training sessions and drills close to the box with situations that are going to happen in the game to make them comfortable and make them believe more in what they have to do. When they have the quality to dribble they have to use it, they do it, it's important when a team not only depends on strikers to score goals, and wingers are able to score goals and make assists your average will be high.
"At Bayern Munich, for example, we had Arjen Robben with a quality one-against-one and he got a lot of assists and goals. When you have that you win a lot of games. When you are just focused on the strikers to score goals you will drop points."
