After his win over Roger Federer in London, Alexander Zverev said: 'I am unbelievably proud. Obviously me and my team have been working so hard for this. I'm a little bit upset now by the whole situation, this is not how I wanted it to end. I don't know what to say right now, I'm sorry. I apologised to Roger. I want to apologise to the crowd as well, he has a lot of fans here. From what he's achieved he deserves to have all the fans in the world. I'm sorry this happened, I didn't mean to upset anybody.'
