With the possibility of split coaches in the Indian team, Sharda Ugra discusses what role Ravi Shastri will play in days to come (1:43)

The BCCI is contemplating appointing separate head coaches for Test and limited-overs formats for the India team. Its official position, as revealed by board secretary Anurag Thakur, was that it would appoint a coach before the South Africa series in October and the cricket advisory committee has been given the freedom to decide on the structure of the coaching staff, but ESPNcricinfo understands the position may be split.

According to board insiders, the BCCI over the last month has approached at least half a dozen overseas candidates. None of them have been forthcoming to accept the full-time role, primarily for two reasons: most of them are associated with a Twenty20 franchise or league and wouldn't like to part ways with a lucrative short-term assignment.

The other factor that has worked against attracting an overseas candidate is the BCCI's emphasis on not letting a foreign coach get assistants of his choice. Instead, the BCCI has stressed that the head coach will have to work with Indian assistant coaches.

It has resulted in eligible overseas coaches being apprehensive of taking charge. The BCCI is understood to have been in touch with three recently-retired cricketers - all of whom have assumed coaching responsibilities with T20 franchises. The high-profile cricket advisory committee comprising Sachin Tendulkar, Sourav Ganguly and VVS Laxman is likely to interact with them over the coming fortnight.

Thakur hinted that team director Ravi Shastri would remain in contention, but stressed it would be up to the advisory committee to formalise the structure and the number of coaching staff required.

"I think it is very important to have a full-time coach for any team. We have taken some time to decide and most probably in the month of September, we will finalise the coach," Thakur said in a chat with Sanjay Manjrekar and Sunil Gavaskar during the lunch break of India's second Test against Sri Lanka on Thursday on Sony Six.

"[Ravi] Shastri is holding the position of the director for the last few months and he has done well with the Indian cricket team, the boys have given us a good feedback about him, so the only issue is if we want a full-time coach then what would be the set-up. We can't be having 10 people with the Indian cricket team.

"So we have left it to the cricket advisory committee to decide how many people will be required, how many coaches will be required, whether a bowling coach, a batting coach, a full-time coach or a director. Let them take a call, come back to BCCI in September and before the South Africa series, I can assure you that we will take a call on that."

Shastri continues to be a contender for one of the positions. Thakur and Shastri, team director for almost a year, are believed to have discussed the roadmap in a meeting in Colombo on Thursday. With Shastri having developed a good rapport with India Test captain Virat Kohli, he could well continue to look after the Test team while the new coach may be in charge of ODIs and T20s.
