'I don't need to win': Serena says shock tennis comeback is not about titles

Serena Williams insists she is not putting pressure on herself to win titles ahead of her shock return to professional tennis.

The 44-year-old, who has won 23 Grand Slam singles titles, will play her first competitive match in four years at Queen's Club this week when she partners 19-year-old Canadian Victoria Mboko in the women's doubles.
