Alessandro Matri saw one penalty parried, but converted the second as Sassuolo sink his former club Cagliari at the Sardegna Arena.

Matri earned a penalty from Leonardo Pavoletti’s clumsy challenge, but saw his spot-kick beaten away by Alessio Cragno.
When Stefano Sensi was brought down by Fabio Pisacane on the hour mark, Matri kept his cool and successfully converted at the second time of asking.
