"And we also are hoping cricket, the sport is one thing so you can keep a good relationship for anyone in any other country.
"So I'm hoping that not only with Pakistan, like India, Sri Lanka, the other countries, we want good cricket. We want more matches to build our cricket or to build our cricket, and I'm hoping that Pakistan is our neighbour country, so it's really good for us to play a lot of cricket with them.
