Pakistan Coach Waqar Younis has said that the near three-month-long tour of England, 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.
He also admitted that the controversies during the England matches were one of the lows of the tour.
"We had successes against Australia 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 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 and fast bowlers Mohammad Amir and Mohammad Asif were provisionally suspended by the International Cricket Council (ICC) and questioned by British police over an alleged plot to bowl deliberate no-balls during last month's Test at Lord's.
