Britain's tennis star Heather Watson, ranked No. 75 in the world, says her footballer boyfriend Courtney Duffus, has been a positive influence in her life, both on and off the court.

Watson told The Herald Scotland: "Actually since we both met each other, we're both doing a lot, lot better. I don't like to let boys have too much influence over me but he has really been a good influence. He's so calm, level-headed. I think you all know I'm quite emotional. He's just really, really supportive."
