Leroy Sane has the potential to reach the pinnacle of world football, but the Manchester City star "needs people to tell him what to do".
That's the opinion of German team-mate Toni Kroos, who believes in the City. The decision of boss Pep Guardiola to drop Sane for the game against Newcastle United could be a shrewd move.
The winger was left out of the Joachim Low World Cup team, which surprised many after an excellent Premier League campaign with the champions, but returned to the international account after being called for this month's matches with France and Peru.
Real Madrid midfielder Kroos praised Sane's ability and potential, but suggested that his temperament might need some work.
"He can be a world-class player, but he needs people to tell him what to do from time to time and to work on himself," said Kroos, who is hoping to appear in his country's UEFA Nations League showdown with France. Thursday.
"That's what Pep is doing at the moment of not selecting him, he wants to provoke it a bit.
" It's clear that you have to find a way to bring it to its best performance. If he is at his best, it is for us, with his qualities, that they are relatively rarely if you look at our squad, a player who enriches us.
"He definitely gives us more options for our game, but obviously only if he is able to prove it on the field"
With Sane assuming the role of spectator, Germany worked in defense of his World Cup title in Russia , leaving in the group stage after the defeats against Mexico and South Korea.
