KUALA LUMPUR: Indonesian coach Indra Wijaya did not deny sending a lawyer's letter to Lee Zii Jia, but declined to comment further on the matter.
When contacted by Timesport today, the 48-year-old Indra said: "I really have no comments on the matter.
"Based on the news, Zii Jia's team have revealed that they had received a letter from me. I cannot say I deny this, but I have no further comments."
On Monday, Zii Jia's sister Lee Zii Yii, who is also his manager, confirmed that they had received a letter from Indra, his former coach.
Zii Yii said the matter is being looked into by their lawyer.
However, Zii Yii declined to comment further on the content of the letter.
Earlier, Timesport had reported that Indra, who was dropped from Zii Jia's team in November, might want to sue the World No 4 for an alleged breach of contract. Indra said he had signed a contract with Zii Jia, which runs until 2024.
Indra, a former national singles coach, left the Badminton Association of Malaysia in February last year to join Zii Jia's independent team.
After guiding Zii Jia to the Asian Championships and Thailand Open titles in May, Indra was surprisingly sacked by Zii Jia's team in November following a string of poor performance.
Former All England champion Zii Jia had a poor start this year, suffering three early exits at the Malaysia Open, India Open and Malaysia Masters.
While admitting that he is affected by all the off-court drama, Zii Jia stressed that his main focus right now is to stabilise his performance.
