Well-informed sources told PTI today that Younis might announce his retirement from one-day internationals during or after the four-match series.
"There has been so much controversy over his selection in the one-day team and plus the clear indications from the team management that they want to build a young team for the World Cup 2019 that Younis is contemplating retirement," one source confirmed.
He said that Younis, 37, has been waiting for the right time to call it a day from 50-overs cricket and the series against England gives him this chance.
Younis was recalled to the Pakistan squad for the series last week after he last played an ODI in the World Cup in Australia and New Zealand in March 2015.

Since March 2013 the senior batsman, who has been in record breaking form in Test cricket, has been out of the ODI squad for long periods and has played just 11 matches in the last two and half years.
Sources close to the national selectors also said they got vibes from Younis that he might quit ODIs next month.
The selectors earlier this year had made an offer to Younis to lead the team in Zimbabwe when Azhar Ali was not available but quit afterwards but he declined the offer saying he will quit on his own terms.
Head coach Waqar Younis during his recent meetings with chief selector Haroon Rasheed in Sharjah assured him that Younis would not sit on the bench and get a chance to play the full series.
