Guidolin remarked: "It was a heart-stopping match and I am satisfied with the performance from my players. I'm particularly happy with Isla, who I think can become a sort of Simone Perrotta character with seven or eight goals per season."
"It doesn't happen every day for Udinese to beat Inter at San Siro," he said of their first victory here since 2004.
"Being top is marvellous and we are notching up the points consistently. It's particularly good that we got this result when 72 hours ago we were on a plane back from France. Having said that, let's just live in the present and not look to the future."
