Photo: Barcelona star Neymar pictured with Serena Williams

Barcelona star forward Neymar has taken full advantage of his free summer by jetting off to Las Vegas. 

Neymar was left out of Brazil's Copa America Centenario squad and took the opportunity to catch some sun to relax and recharge his batteries ahead of next season. 

During his trip the 24-year-old bumped into Serena Williams and posed for a picture with her, before the WTA world number one uploaded the image to Instagram with a caption 'Always be ready for summer. You never know when @neymarjr will show up'.
