Marco Giampaolo felt Sampdoria had “a very European attitude” and caused serious problems for Juventus, despite the 1-0 defeat.
The game was decided by an early Juan Cuadrado diving header, though the Blucerchiati piled on the pressure in the final 15 minutes.
“We were probably a little imprecise in the final third and couldn’t find the right move to score a goal,” Giampaolo told Sky Sport Italia.
“A defeat is never positive, even if it was against the Serie A leaders. Fabio Quagliarella is very motivated and the whole team had a very European attitude, focusing on the attack. There was no point sitting back and defending, because we’d concede eventually anyway.
“Our mission today was to keep the game open until the 95th minute and that is what we did. In fact, Vasco Regini had the chance to equalise in stoppages.
“We were unlucky on the goal, because I’ve never seen Cuadrado with a header before…”
