The much talked about marriage between Indian tennis star Sania Mirza and former Pakistan cricket skipper Shoaib Malik is according to reports going through tough times. Sania has dispelled rumours of rift stating : "Our marriage has not been easy because we are professional athletes and come from different countries and we knew there would be stress on us with time but we have so far managed it well. There are no problems between us at all," said Sania. I came to Sialkot to just relax with my husband and in-laws before the start of my circuit commitments in Europe. I have had a great time and just been busy eating out and shopping to my heart's content because I was out of the media limelight," she added.The speculations of Sania and Shoaib's differences became rife due to the continued distance between the two sporting personalities, but Sania explained that this was understandable since both had their professional commitments."It has not been easy for either of us but we have tried to manage as best as we can and I can tell you I am still as much in love with Shoaib as we were when we got married four years ago," she said.
