Stefano Sensi's goal was the difference as Inter retained their 100 per cent record in Serie A by comfortably beating 10-man Udinese 1-0 on Alexis Sanchez's debut at San Siro.
A nine-minute spell before half-time proved decisive as Rodrigo de Paul was shown a red card for striking Antonio Candreva on the head following the intervention of VAR and Sensi nodded Inter ahead.
