Lahore: Pakistan's controversial fast bowler Shoaib Akhtar has admitted that losing to India in the World Cup semi-final at Mohali is the biggest regret of his life.

Though Shoaib was not a part of the Pakistan playing XI in that match, but he said defeat to India always hurt more than anything else in his cricketing career.

The enigmatic fast bowler announced his retirement from international cricket during the World Cup and was sidelined by the tour selectors for Pakistan's last four games after he had a bust up with teammate Kamran Akmal during the match against New Zealand.

Shoaib also admitted in an interview that he himself didn't like his mood swings that had got him into difficulties numerous times in his career.

Meanwhile, the Chairman of the Pakistan Cricket Board (PCB) Ijaz Butt and captain Shahid Afridi have made some scathing comments about his fitness in the World Cup, but Shoaib has remained tightlipped about it.

Rawalpindi Express, who has kept a low profile since returning from the World Cup, was suppose to come and receive a shield of honour from the organisers of a T20 tournament in Karachi on Saturday night but pulled out at the last moment.

The organisers said Shoaib had informed them he could not make it to Karachi from Lahore because of the death of a close relative.

Asked about his idea of perfect happiness, Shoaib said he got that feeling when his parents were happy.

Shoaib, who has reportedly been signed up to play in the Lankan premier league T20 competition in July, revealed that playing for Pakistan remained his greatest achievement in life.
