Retiring rugby stars: 5 stars who could have played their final game

4. Chris Robshaw (Harlequins)

The 33-year-old announced on in February that he would leave Twickenham Stoop at the end of the season. The flanker is set to join Rugby United New York at the end of the season, but after making over 250 appearances for the London club since his debut in 2005, and after captaining them to their greatest victories, he may not go out in a blaze of glory.
