David Alaba - one of the best and most promising full-back in the world.
Yet it can easily be forgotten that the Austrian is still only 21 as he made his made his debut when he was aged 17 years and seven months.
Since then the Austrian has quickly become one of the brightest talents in world football.
For the past two seasons he has made the left-back position his own at Bayern Munich and in the Austrian national team.
He is the typical modern full-back that bursts up and down the touch-line throughout the game.
A lot of energy, amazing speed, intelligent positioning and a deadly shot - this is David Alaba.
One player who should be very grateful to Alaba is Franck Ribery.
Since Alaba became a first-team starter in season 2011-12, Ribery's game began to improve.
Ribery was a very good winger, but thanks to Alaba now he is one of the best.
Alaba makes space for the Frenchman on the wing and, from there, Ribery manages to use this free space to go forward and score or make assists.
Yet so young, Alaba is already one of the leaders of Bayern Munich and he proved that when he was only 19.
Back in season 2011-12 Bayern Munich faced Real Madrid in the semi-finals in the Champions League.
In the first-half Bayern won a penalty and it was Alaba who took it and scored.
There wasn't a lack of players who can take penalties at Bayern - Arjen Robben, Thomas Müller and many others- but Alaba took the pressure and handled it to score the tone-setting goal.
He even takes the free-kicks and scores from time to time with his most recent goal against CSKA Moscow in the Champions League a few days ago.
It's a big responsibility to take either a penalty or a free-kick - it shows what your status at the club.
At Barcelona, it's Lionel Messi who takes most of the free-kicks, at Real Madrid it's Cristiano Ronaldo, last term Gareth Bale took them at Tottenham. All of them are the leaders of their clubs and Alaba is proving to be one of the leaders at Bayern.
He could even prove to be better than Philipp Lahm, who is currently one of the best full-backs in the world.
Alaba is a bit more versatile than the German. The Austrian can play as a left-back, defensive midfielder, central midfielder and even when needed as a wing.
Lahm is feels most comfortable at either full-back and in the defensive midfielder position.
Alaba showed some amazing vision in the game against CSKA Moscow with the pass to Arjen Robben, who scored the third goal - another thing that Lahm doesn't possess.
Alaba is one of the most complete players, yet many underestimate his abilities due to the fact he is very young.
After a couple of years many will see Alaba as the best full-back, although he is already there.
