AS Roma coach Luis Enrique faces a massive row with skipper Francesco Totti.
Enrique opted to leave both captain Totti and striker Borriello on the bench for their Europa League preliminary round match with Slovan Bratislava.
The Giallorossi lost 1-0 and their qualification for the competition now hangs in the balance.
It is reported Totti and Borriello are furious with Enrique for leaving them on the sidelines in favour of youngsters Stefano Okaka and Gianluca Caprari, says Corriere dello Sport.
Both veterans did come on for the final 15 minutes of the game in Slovakia.
