Kevin Pietersen against Mohammad Amir's return to cricket
Amir made his Test debut in 2009 against Sri Lanka in Galle and soon made a mark with his pace and the ability to swing the ball in both the directions.
Having played 14 Test matches, Amir picked up 51 wickets but his career was stalled when it was revealed that he took part in spot-fixing along with his then teammates Salman Butt and Mohammad Asif.
After confessing his guilt, Amir served a five-year ban and had begun playing domestic cricket in a bid to resume his career for Pakistan.
Strongly iterating that tainted players have no place in cricket, Pietersen is in favour of handing life-bans to any player who indulges in corruption.
“I know Mohammad Amir was only 18 when he got into trouble, and that he was a special talent,” wrote Pietersen in his latest book “Kevin Pietersen on Cricket”.
"I also know that he and Mohammad Asif were from poor backgrounds and were offered a hell of a lot of money for a few seconds' work.
"But I don't care; they should not be coming back.
“I don't feel badly towards them and I wish them well in their lives, but the game is bigger than us, the game will be around a lot longer than us, and we don't have the right to steal from it.
"We play fairly, we play tough, we play positively, we play negatively; people play the way that they want to play.
“But there's no place in the game for corruption, and if you get caught you have to be given a life ban."
The spot-fixing scandal broke during the 2010 Lord’s Test between England and Pakistan, wherein it was disclosed that Amir, Asif and Butt had conspired to bowl no-balls at a particular moment in the match.
Recollecting those moments, Pietersen admitted that the England players were very angry at what the trio had done to the game.
"When the spot-fixing story broke… that day was the worst I've experienced in cricket.
“The guys didn't even want to bowl to them, we didn't celebrate the wickets that we took; everything about it was horrendous.
“We just felt so much anger towards them.
“We could not believe what they'd done.”
Pietersen feels that the return of the tainted trio will be unfair to all those honest cricketers who are working hard to make a career.
"Match-fixing, spot-fixing - I'm fierce about anything like that.
“If you're caught you should never play again, because we have an amazing game.
“There are so many honest blokes out there, trying their hardest and committing to everything to make a living, and if you're cheating then sorry, I'm afraid that's got to be it.”
After a successful showing in domestic cricket, Amir has been drafted by the Chittagong Vikings for the third edition of the Bangladesh Premier League.
