Massimiliano Allegri told Juventus not to be afraid of Atletico Madrid but for one of these teams their worst fears in this season's Champions League are about to become a reality.
Crashing out in the last 16 would be unthinkable for two clubs that were among the favourites when the draw for the knock-out stages was made in December.
"Those that have ambition are not afraid," Allegri said, after his side were drawn to play Atletico, with the first leg on Wednesday at the Wanda Metropolitano.
"It's like a final, we cannot put a foot wrong," Atletico boss Diego Simeone said.
Juventus and Atletico Madrid have reached 12 European Cup finals between them, with last season's game in Kiev the first in five years in which neither had featured.
Atletico went on to win the Europa League instead, proving themselves too strong for Europe's second-tier competition, while Juventus were dumped out by eventual winners Real Madrid, undone by a controversial Cristiano Ronaldo penalty in the 98th minute.
It was Ronaldo's 10th goal in seven games against Juventus, having scored twice in the first leg and twice in the final in 2017 too. Juve beat Real in the semifinals two years earlier but even then, Ronaldo managed a goal in each leg.
There was understandable relief, as well as joy, when the Portugese switched sides last summer and now, there is belief. Ronaldo has not finished in single figures for goals in the Champions league since 2011.
As Lionel Messi said: "They already had a good team and now they have Cristiano Ronaldo."
But with anticipation comes pressure. Juventus are on course to win an eighth consecutive Scudetto but this is the one trophy they crave.
Miss out again and it will be 23 years since they last lifted Europe's premier prize, this time with its most prolific player ever among their ranks.
"We have to be wary of Atletico," Allegri said.
"And we have to find the right moment to score. It's crucial that we get a goal there, otherwise qualification will be very difficult," he added.
