Delio Rossi gave the credit to his Sampdoria players for beating Juventus after playing with 10 men for an hour in Turin.
They seemed doomed when Gaetano Berardi was sent off, but Mauro Icardi’s brace turned it around for a shock 2-1 victory.
“I am very happy, above all for the guys, as this was an incredible achievement,” said Rossi less than a month after taking over from Ciro Ferrara.
“We won against the champions of Italy while playing with 10 men. I made a tactical adjustment during the half-time break, but the lads were amazing in completing this comeback.
“Perhaps Juve weren’t as unstoppable as in previous occasions and it certainly wasn’t their best performance.
“I had to put faith in the players and I think they have the quality needed to survive in Serie A. We have to find at least three teams to put behind us in the table and so far it is happening.”
Rossi revolutionised Sampdoria with a 3-5-2 system and midfielder Angelo Palombo at centre-back.
“Palombo is an experienced player in a very young squad. I don’t know why he was left out for the rest of the season, but he has the right character to play in defence.
“As for Icardi, I find it ridiculous that we were expected to send him to an Under-20 tournament when he’d have a much better chance of making his mark against Juventus.”
