it is illogic to say that PM visit to a match will speed up peace process and it should come from the hearts of people of pakistan when it comes to peace with india and not frequent visits by both the leaders. Pakistan president has interest in cricket and military stuff so he wanted to visit a match in india, but manmohan is one of world's respectful and intelligent leaders and he wouldnt like to waste his time on watching a match,while he has a lot of things to do in india.
hope manmohan refuses even pakistan asks for, which will really raise the pride of the leader and as well india in general,
