Badminton World Number 1 Lee Chong Wei said he was ready to quit from the Badminton Association of Malaysia (BAM) after pulling out from next month's All-England tournament due to injury.

Lee hurt himself after a fall at the newly-opened Academy Badminton Malaysia in Bukit Kiara last weekend. According to The Star, Lee's complaints about slippery mats at the new training centre was not addressed by the BAM.

He said he had been silent about issues concerning the BAM out of respect for his coach Hendrawan who urged him to be patient.

"Now, I have lost my patience and I'm angry... If there is no solution, I'll quit BAM."

Lee tore the medial collateral ligament on his left knee following his fall.

“I've lost my patience with (BAM technical director) Morten (Frost). This injury is the last straw," he reportely said.

"What's even more hurtful was the way Morten handled my injury.

"Instead of asking about my condition, he asked my coach whether I would retire... Why? Doesn't he want me to play on? I'm hurt," he was quoted as saying.

Juniors can spar with seniors

Lee said he had asked for a mat, which was slippery, to be changed, and this message was conveyed through Hendrawan and BAM general manager Lawrence Chew.

When asked to comment, Frost told the daily: "It's best that I don't comment."

The daily said bad blood has boiled between Lee and Frost over several matters, including the Dane's decision to stop junior players from sparring with Lee.

Frost instead divided the men's single players into two groups, which are handled by separate coaches.

"Morten does not want me to spar with the juniors... Why? When I was a junior, I sparred with my seniors. He did this even before the Olympic Games," Lee said.

"And why break the team into two? Won’t the juniors benefit by sparring with the seniors?"
