It took just a few months for Vidic to be pitted against his former United team-mates with current employers Inter, lining up against the Red Devils in the American capital on Tuesday.
The Serbian left behind Old Trafford this summer for San Siro but so far has spent the majority of his days in Nerazzurro touring the USA alongside his new team-mates.
Whilst the 32-year-old’s Beneamata side fell to United at Fed Ex Field earlier this week, however, on Saturday they were able to vanquish Italian rivals Roma in Philadelphia.
And Vidic commented on his fresh adventure at Inter following the 2-0 win over the capital outfit, who will be a major rival for his men for position on the Serie A table in the coming season.
He told reporters: “Yeah, a new challenge, it’s a different league and a different country. Obviously I need time to adapt but so far so good.
“I haven’t had problems adapting to the team. The players have accepted me really well, same with the staff and the manager. Hopefully we’re on the way to building something good.
Vidic struck a glancing header on the stroke of half-time to put Inter on top, somewhat ironically assisted by Dodo - who joined the Milanese club on loan from Roma just weeks ago.
“It was a great cross from Dodo. I was just running to be the first one there and the ball came - my reaction was to put it in the net.”
Inter’s victory means the Nerazzurri are still in with a chance of making the International Champions Cup final in Miami, though their fate ultimately depends on United of all sides.
Vidic noted that reaching the showpiece event in south Florida would be a positive experience for Inter, but needing a Red Devils loss to progress - refused to root against the club he spent four years as the captain of.
“It would be a chance to play against good sides,” he added. “It would be a good test for us if we go to the final, but still we have to wait and see what happens with Manchester United and Real Madrid.
“No, no, no. I didn’t think about it [cheering against United]. We will see. I wish that they play well. I hope they play well.”
