Any Murray has announced that, health permitting, he intends to retire after competing at Wimbledon later this year. The former world number one has battled a persistent hip injury in recent years and has decided the best thing to do is to step away from tennis after competing at his home tournament. However, will the Scottish superstar stick to his word or will he do what many others have done in the past and unretire? There are many examples of sportsmen and women who, having decided to call it a day, were drawn back into competing. Some did it because they were bored, others because they missed the competition, others, well, because they missed the money! We’ve taken a look back at some of the greatest athletes who have unretired and made comebacks to professional sport. Will Murray be the next name added to this list in the future?
