Atalanta celebrated their eighth consecutive Serie A victory, but it was harder than expected to see off 10-man Cagliari.
Luis Muriel converted an early penalty after Arturo Carboni saw red for the Sardinians, so many expected a rout to ensue in Sardinia.
Instead, Alessio Cragno kept the scoreline down and the hosts almost snatched a shock late equaliser.
