Work hard, day after day, year after year, and monumental moments will happen! It's been 5 years since Zizou Ahmad challenged Federer to a match during the U.S. Open press conference. Together with Barilla, @rogerfederer decides to surprise our @tennis_ace_zizou in Switzerland and fulfill his promise. Dreams come true 😉💛 @jmtany @jmtpny #barilla #rogerfederer #johnmcenroetennisacademy #sportime #tennis #tennisnyc #nyc #randallsisland #promise #switzerland #motivation ##tennismatch
