As per the MOU signed between the BCCI and PCB, India and Pakistan are scheduled to play a full Test series in December this year.
But with India refusing to play Pakistan in a full bilateral Test series since 2007, the PCB is confident it can host Bangladesh or Sri Lanka in the slot reserved for the series against Virat Kohli and his men.
"We have opened up discussions with them and are confident now after the succesful hosting of the Pakistan Super League final in Lahore," he said.
An official source in the PCB confirmed to PTI that Pakistan didn't harbor any hopes of India fulfilling its commitment of playing the series.

"We don't see the situation changing this year and we are also planning to move ahead with our legal recourse against them to get compensation for the number of times they have not fulfilled their commitments of giving us home series," the source said.
Sethi said that the PSL final was a beginning and now things would move forward.
"We are now going to build on this final because we have shown everyone we are capable of providing the best security possible for international teams and players in Pakistan," he said.
He said steps will also be taken to hold more matches of the PSL third edition in Pakistan at other venues.
Pakistan has already requested the Bangladesh cricket Board (BCB) to send its security experts to Pakistan for frequent reconnaissance trips so that they can decide to make the tour later in the year.
"It will be a start and than we can see where we go with Bangladesh and Sri Lanka. But we are keen to host a international series this winter," he said.
