Pakistan Coach Waqar Younis [ Images ] has said that the near three-month-long tour of England [ Images ], which was marred by 'spot-fixing' allegations, had been difficult "on and off the field".

Waqar's comments came after the team returned home on Thursday.

"If you take into account the tour to Sri Lanka [ Images ] before we went to England, it was four months on the trot and the tour of England was difficult both on and off the field," The Sydney [ Images ] Morning Herald quoted Waqar, as saying.

He also admitted that the controversies during the England matches were one of the lows of the tour.

"We had successes against Australia [ Images ] which is pleasing, but because of the controversies it was tough against England because you need extra effort to gear the players when you see a report in the newspaper every other day," Waqar added.

Pakistan had arrived in England in late June to play a neutral venue series against Australia and England.

They won both Twenty20 [ Images ] matches against Australia and squared the two-Test series 1-1, but later lost both the Twenty20 matches against England and were defeated 3-1 in Tests and 3-2 in the ODI series.

Pakistan Test captain Salman Butt [ Images ] and fast bowlers Mohammad Amir and Mohammad Asif [ Images ] were provisionally suspended by the International Cricket Council [ Images ] (ICC [ Images ]) and questioned by British police over an alleged plot to bowl deliberate no-balls during last month's Test at Lord's.
