While calls continue being made, from players current and old, asking the PCB to stop forcing BCCI to give their go-ahead for the proposed India vs Pakistan series in December, the Pakistan Cricket Board chairman Shahryar Khan is clearly not ready to heed to those requests yet.

After quotes from the chairman came out earlier this week, which suggested he was not too optimistic of the series going ahead, a new bunch of them have come out on Friday, with the threat of "boycott" looming large.

The BCCI signed an MOU with the PCB, saying India and Pakistan will play six bilateral series in eight years, with the first one of those tentatively scheduled for December.

It is supposed to be a "home" series for Pakistan, which means playing in the UAE, and Khan has been putting as much pressure as possible on the BCCI to push the series through, considering the financial windfall it will bring to the PCB.

However, with the troubled relations between the two countries, it remains unlikely that the Indian government will give their thumbs-up to the bilateral series.

Khan said he is frustrated by the fact that the BCCI have not yet spoken to the relevant authorities in the government about the possibility of India playing Pakistan, with the PCB chairman threatening a boycott of all India vs Pakistan matches in the future, be that ICC or ACC (Asian Cricket Council) tournaments.

"Nothing is final or decided as yet but if the Indian Board officially backs out of the series, then we have the option of boycotting all matches against them in ICC and ACC events as well," Khan was quoted by the PTI as saying in the Express newspaper.

"I sent the letter on 28 August and I am still waiting for a reply. They [the BCCI] should tell us whether they want to play the series or not.

"Because if they say they don't have government clearance and refuse to play the series, then we reserve the right to act against the Indian Board for not honouring an agreement at every level.

"I am not saying we have decided to do this or we will do it, but certainly if we don't get to host our home series in December, then we have to consider appropriate action as well."

India and Pakistan have only played in multi-team tournaments in the recent past – the latest one coming in the ICC Cricket World Cup in Australia and New Zealand earlier this year -- with the last bilateral series between the two rivals played in 2012.
