The oil tycoon is on the verge of selling the Nerazzurri and was therefore keen to remind the players of their responsibility to the shirt
The oil tycoon is on the verge of selling the San Siro giants to Indonesian businessman Erick Thohir, meaning his reign at the Giuseppe Meazza is about to draw to an end.
Consequently, Moratti, who has been criticised in some quarters for handing Inter over to an outside party, wanted to address the players during a team meeting on Saturday.
"Moratti helped me to urge the players to honour the jersey and give the best for this club," Mazzarri explained to reporters on Saturday.
"I believe that if the president has taken certain decisions, he, being in love with the club, did it for the sake of Inter and this must be accepted."
Mazzarri revealed that Inter have been further boosted by the progress Argentine duo Diego Milito and Walter Samuel are making from their respective injuries.
"Milito is looking much better, more agile," the former Napoli boss enthused. "I have to see how many minutes he's got in him but he's on the right path. The only thing is that we mustn't rush him.
"Samuel is fine, he's recovered now and is back in training. He's available for selection although he's obviously not up to match speed yet."
Inter, who have accrued seven points from their first three games, take on Sassuolo on Sunday at 12:30CET.
