A second-half strike by forward Armand Lauriente gave Sassuolo a surprise 1-0 win over nine-man Atalanta in Serie A on Saturday, ending the visitors' unbeaten run in the Italian top-flight this calendar year.
Atalanta, who ended January with a 1-0 defeat to Inter in the Coppa Italia quarterfinals, suffered their first Serie A loss since the league resumed after the World Cup break.
Sassuolo, coming from an impressive 5-2 win over title holders Milan in their last outing, moved up to 15th and increased their cushion above the relegation zone to 10 points.
"We can say that we are healed," Sassuolo midfielder Davide Frattesi told DAZN.
"After Milan we didn't get too excited because one swallow doesn't make a summer, but we needed a couple of important results to say that we are cured.
"The attitude has changed, it's a fundamental thing. We talked about it in the dressing room, something was wrong and we solved it. The quality has always been there, even in the most difficult moments, and that's the most important thing."
Sassuolo took the lead in the 55th minute through Lauriente who unleashed a brilliant long shot from the edge of the box, sending it inside the far post for his fourth goal in his first season in Serie A.
Atalanta were reduced to nine men in stoppage time when substitute Luis Muriel saw a direct red card for what appeared to be an argument with the referee.
Jose Mourinho's side moved to 40 points from 21 games and are third in the standings, level with second-placed Inter who host Milan on Sunday.
