Royal Challengers Bangalore owner Vijay Mallya bought Yuvraj Singh for a massive for 14 crore but after the end of the auction of Day 1 he lodged an official complaint with the IPL Governing Council.

Mallya lodged an official complaint to the IPL Governing Council, saying his franchise coughed up Rs 4 crore more on buying all-rounder Yuvraj Singh on the first day of the players' auction.

RCB had almost bought Yuvraj for Rs 10 crore when Kolkata Knight Riders joined in the bidding, and eventually the left-handed batsman was sold for Rs 14 crore to the Bangalore outfit.

Mallya, however, said that the hammer had fallen at Rs 10 crore for Yuvraj.

"The hammer did go down at Rs 10 crore. Normally, my understanding is that when the hammer falls down, that's the final," he said.

"We have written to the IPL Governing Council regarding this. I am hopeful that they (IPL GC) will consider the matter," Mallya told a television channel.
