Angelo Alessio's final Serie A game on the touchline for Juventus came to an end with a 3-0 derby victory over Torino on Saturday and he admitted the encounter was a tough one.
The assistant coach, who has stood in for the banned Antonio Conte since the start of the season, cut a nervous figure before a second-half double from Claudio Marchisio and Sebastian Giovinco's strike settled the contest.
"It wasn't easy to play against such a well-organised side," he told the club's official website.
"We had a few difficulties in the first 20 minutes and the game changed following the sending-off, which was an unquestionable decision.
"Thank goodness [Emanuele] Giaccherini didn't have his foot on the ground, otherwise he would have hurt himself."
The Bianconeri tinkered with their usual 3-5-2 system and Alessio was happy to see the changes reap the rewards that he had sought.
"The change in formation? We didn't feel it was worth risking [Giorgio] Chiellini and preferred to go with the 4-3-3 used on many occasions last year," he added.
"But our system is 3-5-2 and we'll use that in Donetsk [against Shakhtar], where Chiellini will come back into the fold. Antonio will be back on Sunday; I can't wait for him to return and take his place on the bench."
