agassi is`t more waker defender , but with his great agressive tennis and with the best return of serve of all time , he would destrot djokovic , murray and nadal serves
But Djokovic and Murray would have murdered his serve too. An Agassi-Djokovic match would be a baseline borefest, they are pretty similar each other, great ROS, shitty volley, exceptionnal balance...
They are both great in the AO, good in the French+USO, average in Wimbledon.
It would be a toss up, really, but given his physical skills, Agassi would have a hard time in playing Djokovic and Federer/Murray in a row.
