Fiorentina were held to a second straight draw after playing out a goalless stalemate against Sassuolo in an entertaining Serie A clash filled with chances.
While the result stretched Fiorentina’s unbeaten league run to six matches, their inability to convert opportunities proved costly.
David de Gea was tested early, making a fine save to keep out Ismaël Koné, before Stefano Turati responded at the other end by denying Albert Guðmundsson with a clever stop.
Fiorentina struggled to impose themselves in the opening half and nearly fell behind when Manor Solomon missed a golden chance, firing wide from close range after a precise delivery from Jack Harrison.
The hosts improved after the interval, but Turati proved difficult to beat, producing key saves to stop Guðmundsson from close range and later parrying a powerful strike from Dodô.
Sassuolo, however, remained dangerous on the break and came closest to scoring when Andrea Pinamonti hit the post from point-blank range.
Fiorentina continued to carve out better openings but lacked precision in decisive moments, with Guðmundsson missing another good chance and Nicolò Fagioli seeing a late effort drift wide.
The draw leaves Fiorentina nine points above the relegation zone with four games to play, while Sassuolo solidify their place in the top half of the table.
