Following his victory, the tennis legend acknowledged Messi's presence at the venue as he said: "Amazing to have him. It is a great honour to play, probably for the first time, in front of him live. I am really grateful he was here with his son and the family. I admired him, of course, as most of the world did for most of his career, and it is amazing he still keeps going. We are actually the same age, born in 1987, so it is nice to have him around."
