Nike London is honouring the legacy of Serena Williams.

As the tennis sensation continues her march towards her eighth Wimbledon title, Nike's latest limited-edition drop is a tee that celebrates Serena's status as an honorary Londoner.

The 'Unbeatable Serena' tee is only available to Nike+ members, who can win a T-shirt buy telling Nike why they think Serena is "unbeatable".

Winners will be selected and t-shirts couriered to a select group on Friday 13th July.

To enter, head to nike.com.
