Stylish batsman Yuvraj Singh may not be in the best of form, but Indian skipper Mahendra Singh Dhoni feels he needs backing as it is important to show confidence in him.

Yuvraj has not been among the runs in the ongoing series against the West Indies and his customary weaknesses against the short ball showed as he got hit by a Fidel Edwards delivery in the first innings of the Kolkata Test at the Eden Gardens here.
