The match at Old Trafford could well be a possibility for Federer, who is taking some time off from the game and is most likely expected back at the Swiss Indoors in Basel in a month.
British tabloids report that football-mad Federer believed he could have made it on the pitch had his iconic tennis talent not burst to the fore as a youngster. Despite dedicating himself to a history-making career on the court, the beautiful game has never been far from his thoughts.
"I'd like to think I could have been a footballer. I was an attacking midfielder or striker. I was a good leader and I think I could have made a good captain," Federer has said in reference to his football interests.
"My first heroes were Italian players like Roberto Baggio and Toto Schillaci. After that I used to love watching Ronaldo, Luis Figo and Zinedine Zidane.
"Tennis took over really for me when I was 12. My tennis schedules were so busy that I couldn't combine them with other sports, including football. I'd like to think I could have been a footballer if I hadn't had to give up."
