I already mention in above post it's just announcement and mind game from them because they are feeling some pressure against Pakistan, so they are trying to have some better positive way from Pakistan after this announcement. Most chances they will never arrive in Pakistan and if they have to visit then surely few players will be not feeling good, and they will withdraw because they have history of things like this not only in case of Pakistan they have done already against South Africa, but good thing is they never do these things against England and India because these two have big impact on their own business.
