Heynckes: Bayern should have signed Werner
Werner came through the youth ranks at VfB Stuttgart but was snapped up by RB Leipzig in July 2016, following their first-ever promotion to the Bundesliga.
The 21-year-old has since become one of the club's star players and has already scored eight goals and provided three assists for Leipzig this season.
"Bayern should have signed a player like Timo Werner from Stuttgart a few years ago," Heynckes told Die Welt.
"He could have learned here very well. You have to reach out for young talents in time.
"The best players must play. It does not matter whether they are old or young.
"Do you think that a Franck Ribery can always expect to play? No. When he is not on form, he will not play.
"As I said, you have to look after good, young players in a timely fashion. You have to challenge, speak, lead and motivate them."
