Torino manager Sinisa Mihajlovic joked that he regrets giving teenage goalkeeper Gianluigi Donnarumma his debut after a 3-2 defeat to Milan at San Siro on Sunday.
The Serbian tactician was sacked by Milan in April last season, and started the new Serie A campaign at the helm of Torino with a return to his former employers.
Andrea Belotti and Daniele Baselli scored for Il Toro, but it was not enough to earn a point after Colombian striker Carlos Bacca hit a hat-trick for the Rossoneri.
Baselli’s goal arrived in the first minute of added time, and Belotti had a chance to salvage a point with a 96th-minute penalty, but Donnarumma saved it, much to the frustration of his former boss.
"If I had known he was going to save the penalty, I wouldn't have given him his debut," Mihajlovic told Sky Sport Italia.
"I smiled because I knew 'Gallo' was going to miss. Unfortunately, I'm almost always right.
"I went to reassure him afterwards, these things happen and the next time we get a penalty he won't be taking it.
"I don't want to seek excuses, all teams have injured players and ours would be different with them in it, but that's natural. "We made individual errors and that is what cost us."
