‘Master Blaster’ Sachin Tendulkar is not satisfied with his achievements so far and is aiming 15,000-run mark and the 2011 WC.

“I am not pleased yet with what I have done,” Tendulkar said in an interview to Wisden Cricketer.

“Sunil Gavaskar has told me that I have to get to 15,000 runs. He said he would be angry with me and would come and catch me if I didn’t. I admire him so much and to score that many would be a terrific achievement, but that is not the only aim,” the 36-year-old star batsman said.

His other aim being to “win the World Cup in 2011″. Sachin Test-run tally stands at 12773 right now, which he scored at an average of 54.58 from 159 matches.

He also spoke about playing with pain most of the times.

“I always play in pain, all the time. I played with a broken finger for the last three months, but you know when pain is manageable or not, and most of the time I can do it,” he said. “I can still do what I did when I was 25 but the body is changing, so your thought process has to change too. I have had to change how I think, which is about taking less risk.”

He, meanwhile, disagreed with former Australia coach, John Buchanan, who has alleged that Tendulkar had become susceptible to the short ball early in his innings because of a lack of footwork.

“It is only his opinion; John Buchanan doesn’t have to be right all the time. If I couldn’t handle short deliveries, then I wouldn’t still be scoring runs,” Sachin pointed out.

“Maybe he needs to change his opinion. There must be something very wrong with all the bowlers around the world that they have allowed me to score so many runs.”

Sachin also had a compliment for Virender Sehwag. “I would say Virender Sehwag comes closest to my style,” he said.

Tendulkar also that retirement was not on his radar yet, but he would know when to quit cricket. “I will know when it is the right time, I won’t have to be dragged away. I am the person who will make the decision and I will know whether I still belong.”

But he admitted life after cricket wouldn’t be easy. “It’s a scary thought. It has been there for my whole adult life, it will be difficult, I have been around for a long time, I can imagine when I finish I will long to face just 10 more balls but you have to move.”
