Two defeats in successive matches against the USA and India had left Pakistan teetering on the brink in Group A with three teams above them in the race for Super 8 qualification.
Mohammad Amir, who played 36 Tests, 61 ODIs, and 50 T20Is in which he scalped a total of 259 wickets, recently announced his retirement.
Shoaib Akhtar suggested that Amir shouldn't have retired for his issues with the management but instead, he "should have bowled well and improved his performance".
Mohammad Amir, the 28-year-old left-arm pacer has said that he would release a detailed statement after reaching Pakistan in a few more days.
Mohammad Amir, after making his international comeback in 2016, played all the three formats for Pakistan almost without rest for a span of three years.
During the time of his Test retirement, Mohammad Amir boasted impressive numbers with 119 wickets from 36 matches at an average of 30.47.
Pakistan's players went to the Sri Lanka dressing room to thank them soon after the home team posted a convincing 263-run win in the second Test of their first home series in a decade.
In the last few years, Amir emerged as Pakistan's leading bowler in across formats and was expected to hold the baton in the Test Championships as well.
Riaz played 27 Test matches and picked 83 wickets with a best bowling figure of 5/63 in an innings. The left-arm pacer last played in the longest format against Australia in October 2018.
Arthur felt Amir would have been one of the best Test fast bowlers in Pakistan's history had he not lost those five years to the spot-fixing ban.
