Well a lot of other sources are saying that Butt has indeed contacted Yousuf however has not heard back anything from yousuf yet.
With all this due respect to yousuf, this is the exact situation he wanted for his come back. Remember when he announced his retirement, he said that he is* filhal *retiring from test cricket and then couldn’t explain to journalists what his filhal meant?? The ideal situation for him to come back was PCB asking him to come so that he can say, see I took my decision back not because I wanted to be back but because they wanted me to come back.
Probably the only thing Yousuf will now be regretting is his annoucement few weeks ago about resuming international cricket in October.
