When will Yuvraj learn?

India Blue won the the recent NKP Challenger Trophy. But Yuvraj Singh's contribution to the team's victory was almost nil. He was out for some poor shots in this series. He doesn't seem to be learning from his mistakes. He was trying to play too many shots too early in the innings.
His place in the team is going to be in danger. A lot of talented youngsters are there waiting for the place in the national team. Yuvraj must be aware of this and he has to perform to keep his place safe.
Yuvraj was in the form of his life one year ago. He was named as the man of the series in three consecutive series against South Africa (joint with Graeme Smith), against Pakistan and England. He scored three centuries and four half-centuries in fifteen matches in those 3 series. It helped him to make it into the top ten of the ICC ODI batting rankings.
Though he is there in the international cricket for around 8 years, he is yet to make his mark in the test cricket. Though he got many opportunities in tests, he did not utilize them. He already lost his place in the test team. And if you consider his recent ODIs, he scored 72 runs with an average of 14.40 in 5 matches against SriLanka. He struggled a lot against the spinners. And it's still the main concern for Yuvi.
In the last 12 months, he has not played a big innings. He scored 840 in 27 matches with an average of 35.00. After his successful performance in the T20 world cup last year, Yuvraj has been playing that kind of shots in all formats of the game. He was trying to hit every ball out of the ground. It's going to be difficult for Yuvraj to keep his place safe in the team(atleast ODIs) unless he changes his attitude.
C'mon Yuvi...you are a match winner...make a strong come back...
