Yaya Toure has warned Manchester City forward Gabriel Jesus against complacency following the Brazilian's stunning start to life in the Premier League.
Jesus, making his City debut in last month's meeting with Tottenham, has scored three and made one more in his last two games under Pep Guardiola and has forced Sergio Aguero out of the Catalan's starting XI.
Summer arrival Leroy Sane has also enjoyed an impressive run of form, scoring three goals in his last five outings, following a difficult start to life in Manchester.
And although Toure has liked what he has seen from the exciting newcomers, he has warned them they must continue to push themselves in order to be a success at the Etihad.
"The new guys have a big potential,' Toure told the Daily Mirror. "Sane has been unbelievable, Raheem has always been very good, and we are seeing what Jesus can do. But sometimes, when you are young, you start to think that football is easy.
"They have got to keep working hard, pushing all the time to improve, because the moment you think you have arrived can also be the moment when you start to slip.
"That's why the experienced players are important. Me, Vincent [Kompany], David [Silva], Zaba [Pablo Zabaleta], we are pushing them all the time to get better.
"This club is all about winning trophies. When new players come in, they have fantastic skill, but they also have to learn the winning mentality."
Toure, now established in Guardiola's preferred XI following a first-team exodus imposed by the Catalan, also believes he can play a significant part at City for at least another five years.
The 33-year-old has made 11 Premier League starts this season, scoring four, though was previously linked with a move away from the club during the early parts of the season.
Toure's city contract expires at the end of the season and there is not thought to be an extension on offer to him at present, though Toure insists he has at least five years left in him at the top level.
'I can go on for another five years," he added. "You don't believe me? OK, let's make a bet."
