Thanks for all your messages yesterday and today! I suffered ankle ligament damage, but I think it isn't as bad as it looked. 😉 My rehab will start soon and I'm motivated to be back on the pitch as soon as possible! 🔥⚽🔥 #inSané #LS19 @ManCity pic.twitter.com/WQCpdFrgjO— Leroy Sané (@LeroySane19) 29 January 2018
