Stevan Jovetic struck twice to clinch the three points.
"Winning with a last-minute goal was very exciting after piling pressure on Udinese for 90 minutes," said the Coach.
"We kept our shape and that's to the great credit of this team. It was a good performance, especially being the first of the season.
"However, we mustn't let ourselves get swept up by easy enthusiasm. In the first half we had few efforts on goal, something that changed after the break. We can improve a great deal, but let us enjoy this victory for now."
