Injuries and apparent decline

Tendulkar continued his good form in Test cricket in 2001 and 2002, with some pivotal performances with both bat and ball. Tendulkar took three wickets on the final day of the famous Kolkata Test against Australia in 2001. Tendulkar took the key wickets of Matthew Hayden and Adam Gilchrist, centurions in the previous test.

In the 2002 series in the West Indies, Tendulkar started well, scoring 79 in the first test, and 117 in the first innings of the second. Then, in a hitherto unprecedented sequence, he scored 0, 0, 8 and 0 in the next four innings, getting out to technical "defects" and uncharacteristically poor strokes. He returned to form in the last test scoring 41 and 86. However, India lost the series. This might have been the beginning of the "decline" phase in his career which lasted till 2006.

Tendulkar made 673 runs in 11 matches in the 2003 Cricket World Cup, helping India reach the final. While Australia retained the trophy that they had won in 1999, Tendulkar was given the Man of the Tournament award.

He continued to score heavily in ODI cricket that year, with two hundreds in a tri series involving New Zealand and Australia.

The drawn series as India toured Australia in 2003/04 saw Tendulkar making his mark in the last Test of the series, with 241* in Sydney, putting India in a virtually unbeatable position. He followed up the innings with an unbeaten 60 in the second innings of the test. Prior to this test match, he had had an unusually horrible run of form, failing in all six innings in the preceding three tests. It was no aberration that 2003 was his worst year in test cricket, with an average of 17.25 and just one fifty.

He scored an unbeaten 194 against Pakistan at Multan in the following series. The 194 was controversial in that he was stranded prior to reaching his double century as a result of a declaration by Rahul Dravid. In meeting with the press that evening, Tendulkar responded to a question on missing 200 against Pakistan by stating that he was disappointed and that the declaration had taken him by surprise.[52] Many former cricketers commented that Dravid's declaration was in bad taste.[53][54] The media noted at the time that the decision had apparently been made by Sourav Ganguly,[55] and Ganguly himself later admitted that it had been a mistake.[56] The controversy was put to rest when Rahul Dravid, Sachin Tendulkar and coach John Wright spoke to the media after the team's victory and stated that the matter was spoken internally and put to rest.[57]

Tennis elbow then took its toll on Tendulkar, leaving him out of the side for most of the year, coming back only for the last two tests when Australia toured India in 2004. He played a part in India's victory in Mumbai in that series with a fast 55, though Australia took the series 2–1.

On 10 December 2005 at Feroz Shah Kotla, Tendulkar scored his record-breaking 35th Test century, against the Sri Lankans.

In the test series in Pakistan in 2006, Sachin failed to get going in all three innings despite the pitches being flat tracks. In the third of those three innings, he was bowled comprehensively after making 26, and ended up on all fours. This prompted The Times of India to publish an article entitled "Endulkar" in which TOI opined that Tendulkar's batting prowess had declined and his career had slid permanently.

On 6 February 2006, he scored his 39th ODI hundred, in a match against Pakistan. He followed with a run-a-ball 42 in the second one-day international against Pakistan on 11 February 2006, and then a 95 in hostile, seaming conditions on 13 February 2006 in Lahore, which set up an Indian victory.

On 19 March 2006, after scoring an unconvincing 1 off 21 balls against England in the first innings of the third Test in his home ground, Wankhede, Tendulkar was booed off the ground by a section of the crowd,[58][59] the first time that he had ever faced such flak. Tendulkar was to end the three-Test series without a single half-century to his credit, and news of a shoulder operation raised more questions about his longevity. Tendulkar was operated upon for his injured shoulder. In July 2006, the Board of Control for Cricket in India (BCCI) announced that Tendulkar had overcome his injury problem following a rehabilitation programme and was available for selection, and he was eventually selected for the next series.

Tendulkar's comeback came in the DLF cup in Malaysia and he was the only Indian batsman to shine. In his comeback match, against West Indies on 14 September 2006, Tendulkar responded to his critics who believed that his career was inexorably sliding with his 40th ODI century. Though he scored 141*, West Indies won the rain-affected match by the D/L method.

In the preparation for the 2007 Cricket World Cup, Tendulkar was criticized by Greg Chappell on his attitude.[60] As per the report, Chappell felt that Tendulkar would be more useful down the order, while the latter felt that he would be better off opening the innings, the role he had played for most of his career. Chappell also believed that Tendulkar's repeated failures were hurting the team's chances. In a rare show of emotion, Tendulkar hit out at the comments attributed to Chappell by pointing out that no coach has ever suggested his attitude towards cricket is incorrect. On 7 April 2007, the Board of Control for Cricket in India issued a notice to Tendulkar asking for an explanation for his comments made to the media.[61]

At the Cricket World Cup 2007 in the West Indies, Tendulkar and the Indian cricket team, led by Rahul Dravid had a dismal campaign. Tendulkar, who was pushed to bat lower down the order by the Greg Chappell had scores of 7 (Bangladesh), 57* (Bermuda) and 0 (Sri Lanka). As a result, former Australian captain Ian Chappell, brother of the then Indian coach Greg, called for Tendulkar to retire in his column for Mumbai's Mid Day newspaper.[62]

During this period from about 2002 to 2006–7, Tendulkar's batting often seemed to be a shadow of its former self. He was inconsistent, and his big knocks mostly came in sedate, accumulative, uncharacteristic fashion. He seemed to have either cut out or lost the ability to play many shots, including the hook and pull and many other aerial strokes. He also developed a tendency to go without scoring much for long periods and become overtly defensive. While players such as Ponting and Kallis were at the peak of their careers, Sachin's seemed to be in terminal decline. There were several calls from him to retire too.

However after the 2007 World Cup, his career had a second wind and his consistency and form have returned.
