NEW DELHI: India head coach Gautam Gambhir, facing mounting scrutiny, on Wednesday said it was ultimately up to the BCCI to decide his future following the team's 2-0 Test series whitewash at the hands of South Africa.

Speaking after India's humiliating 408-run defeat in the second Test at Guwahati, which handed the visitors a clean sweep, Gambhir also reminded everyone of the successes achieved during his tenure, including notable victories in overseas conditions and past ICC tournaments.

"It is up to the BCCI to decide my future. But I am the same guy who got you results in England and was coach for Champions Trophy," Gambhir said at the post-match press conference referring to India's title-winning run in the Champions Trophy and a gruelling 2-2 draw against the English in their own backyard earlier this year.

"The blame lies with everyone and starts with me," he conceded in his first reaction after the 0-2 drubbing.

"We need to play better. From 95/1 to 122/7 is not acceptable. You don't blame any individual or any particular shot. Blame lies with everyone. I never blamed individuals and won't do it going forward," he added.

Under Gambhir's tenure, India have lost 10 of their 18 Tests, suffering back-to-back home whitewashes - first against New Zealand last year and now against South Africa.

The defeat in Guwahati was India's heaviest loss by runs in Test history, compounding the pressure on the under-fire head coach.

Gambhir has of late attracted criticism for frequent changes in the team and his inclination to focus more on all-rounders than specialists in the traditional format.

"You don't need the most flamboyant and talented cricketers to play Test cricket. What we need is tough characters with limited skills. They make good Test cricketers," he said.
