Stefano Sensi headed the only goal just before the break as Inter Milan went top of Serie A with a 1-0 win over 10-man Udinese.

The visitors had Rodrigo De Paul sent off in the 35th minute following an off-the-ball incident involving Inter’s Antonio Candreva.

Dries Mertens scored once in each half as Napoli eased to a 2-0 win over Sampdoria, who are still searching for their first points of the season after three games.
