While mystery shrouded the circumstances surrounding Pakistan coach Bob Woolmer's death, his wife Gill said on Wednesday that she knew all was not well although her 'tired' husband never spoke to her about any problems.

Gill said she was aware that Woolmer was struggling to cope with the stress that his job brought.

"He never mentioned anything about being under pressure but obviously, seeing his pictures on the television, it was enough to know that he was under pressure by the expression on his face," she said.

Gill revealed that Woolmer was in regular touch with her during the ongoing World Cup and had told her that he was tired of living out of hotels.

"The last time I spoke to him was some time last week. He was in touch with us everyday," Gild told NDTV. "He was tired. His was a very tough job and involved a lot of travelling. The long journeys and (adjusting to the) time differences made it a very difficult job."

The 58-year-old player-turned-coach died on Sunday under mysterious circumstances hours after Pakistan lost to minnows Ireland in the World Cup.

Jamaican police have said that the autopsy reports were inconclusive about the reasons for his death and they were investigating the possibility of any foul play.

Earlier, Woolmer's son Russell had also spoken about the South Africa-based Englishman being under stress and had cited it as one of the reasons for his shocking death.
