Kevin Pietersen has brushed off concerns his latest Twitter outburst could land him in trouble with the England and Wales cricket Board and has no plans to tone down his comments on the micro-blogging site.

The former Hampshire batsman launched an attack on Nick Knight last Friday, questioning the former England opener's credibility as a Sky Sports pundit.

The 31-year-old wrote: "Can somebody please tell me how Nick Knight has worked his way into the commentary box for the Tests?? Ridiculous."

The tweet is thought to have not gone down well with the ECB, who two years ago imposed a set of guidelines which players must adhere to.

Players face being fined if they break the rules, but Pietersen, who was fined following an outburst against selectors in 2010, is not worried his latest comments will lead to him being sanctioned.

"Not at all," Pietersen said when asked whether he was worried about being fined. "I haven't seen (that story)."

When asked whether he would consider toning down his comments on the site, he added: "No, not at all, no. I won't stop tweeting, no."

Pietersen was one of the few players to come away with his reputation in tact from a torrid winter that saw England suffer whitewashes against Pakistan and India before some pride was restored to the number one ranked side in the world when they fought back to draw their two-Test series in Sri Lanka.

The Surrey batsman hit 151 in Colombo and has been successful in the shorter forms of the game of late, but could only manage 32 and 13 against West Indies at Lord's, where England emerged with a nervy five-wicket victory.

It was under-pressure captain Andrew Strauss who swung the game in England's favour with the bat thanks to his score of 122 - his first century since November 2010.

Pietersen, who went two years without scoring a Test hundred, was delighted to see the 35-year-old return to form.

"I never doubted him, most definitely," said Pietersen, who was supporting Chance to Shine's Brit Insurance National Cricket Day at Johanna Primary School in central London today.

"Strauss is a fantastic guy and I was more happy for him scoring that hundred than I have been for any other team-mate when they have scored a hundred. I loved the fact that he did that.

"I have been through a period where I didn't score a hundred for a while and since then I have scored many.

"This sort of thing just happens. Someone is going to get criticised. That's just what happens in our job.

"He is a great bloke who has scored 19 Test hundreds and has captained England to home and away Ashes series. It was brilliant for English cricket that he got a hundred."

Without the likes of Chris Gayle and Ramnaresh Sarwan, the tourists were expected to be easy fodder for the hosts at Lord's, but Shivnarine Chanderpaul demonstrated why he is ranked number one in the world with scores of 91 and 87 while Kemar Roach and Shannon Gabriel excelled with the ball.

Gayle could return for the Windies for Friday's second Test at Trent Bridge after his spell in the Indian Premier League came to an end.

The former captain's presence would add experience and clout to the tourists' batting line-up but Pietersen is looking forward to locking horns with the towering batsman.

"He's a superstar and he is one of my real good mates in cricket. I love the way he plays," Pietersen added.

"It will be brilliant for the game if he comes back to play this Test match. He is an entertainer. People want to watch entertainers. They don't want to watch people blocking the ball."

The ECB were unavailable for comment regarding Pietersen's tweets when contacted today by Press Association Sport.

Meanwhile, the ECB today announced that England's winter tour to India will comprise of four Tests, five one-day internationals and two Twenty20s.
