Matt Oldfield grew up in Southampton, playing football with his brother Tom. The two brothers are the authors of the bestselling Ultimate Football Heroes series – fun football biographies that tell the exciting life stories of superstars like Gareth Bale, Lionel Messi and Mo Salah, from the playground through to the pitch. The Johnny Ball books are Matt's first fiction series. Tim Wesson draws in for both children and adults. He illustrates for France Magazine every month and has also illustrated for other clients including Habitat, SWATCH, Paperchase, BBC, Peagreen and many others.
