Misbah, 42, was compelled by the Pakistan Cricket Board not to retire from Test cricket late last year and lead the team on the England tour and a PCB official said the captain now wanted to clearly outline his future plans before leaving for England.
"Misbah will officially announce it in press or would convey it to the board till Friday of till when he wants to continue playing international cricket," he said.
His critics and supporters believe that the tour to England will define Misbah's place in Pakistan cricket history as Pakistan in the last four to five years has played its home series in the United Arab Emirates on generally flat pitches.
Ironically, Misbah was not part of the Pakistan squad that went to England in late 2010 for a tour which saw the infamous spot-fixing scandal erupt in the fourth and final Test at Lords.

The 42-year has not played a Test in England until now and his deputy Azhar Ali, is the only batsman from the current batting lineup who played the Lord's Test.
But Misbah made it clear he remained confident about the team's chances in England as it boosted a strong bowling line up and a confident batting line up.
"Our batting line is way more experienced than the side which toured England in 2010. Results will be better."
Misbah admitted that the English pace attack posed a serious challenge for the Pakistani batsmen in their home conditions but said the batsmen have been told they must be prepared to stand up and be counted.
Misbah has twice led Pakistan to Test series wins over England in 2012, completing a 3-0 whitewash and last year as well but both series were played in UAE.
He said Pakistan has a good opportunity to leave a historic mark in the series.
Misbah said Pakistan had two potential match-winning bowlers in Muhammad Aamir and leg-spinner, Yasir Shah while the other bowlers were also capable of taking regular wickets.
