The Serie A champions welcomed a spirited Shakhtar Donetsk side to Turin, and found themselves behind midway through the first half after Alex Teixeira tucked away the rebound from team-mate Willian's shot. Juventus defender Leonardo Bonucci scored a spectacular equalizer moments later when he lashed an Andrea Pirlo corner past a flailing Andriy Pyatov.
Carrera admitted to the club's official website that his players were nervous ahead of their first Champions League fixture at the Juventus Stadium.
"We were a little tentative at the start, but we knew that Shakhtar were a tough team to face," Carrera stated.
"We conceded, but then managed to immediately get back on level terms and proved a match for them after that."
The Bianconeri attacked struggled at times to unlock the defence of their Ukranian opponents, a failing which the Italian believed was caused by fatigue.
"Tiredness was also a factor, given the sheer amount of games played recently. We’ve got less time to work, which is a problem compared to last year and today we lacked our usual fluency," Carrera said.
"There are strong teams in the Champions League and at least two in our group. We’ll do our best and will give it a good go right until the end."
Midfielder Claudio Marchisio echoed Carrera's sentiments, but he remained confident the team would achieve qualification from the group stages of the competition.
"We didn't start very well but then we managed to get a handle on them and could even have gone in front. There were a few tired legs out there towards the end though and – credit to our opponents too – we might have lost it," Marchisio confessed.
"Now we have a double header against Nordsjaelland which, on paper at least, should be a bit easier. We still need to approach them very carefully though. We've only just got back in the Champions League and we all need to prove that we're good enough to be here."
Juventus travel to Siena for their Serie A fixture this Sunday.
