Talking to 'Sky Sports News', owner Tony Bloom said, "The Manchester United game we played very well, I thought we deservedly beat them,.
"It was our last home game, we were definitely not safe, although we were looking OK and obviously retrospectively we would have been safe even if we'd lost that game," he added.
"But with Manchester City and Liverpool away coming up, it was the most likely game to get points.
"A draw we would have been delighted with but a win guaranteed it so the excitement of the fans, I think it goes down as one of the great games."
Bloom has been the chairperson at the club since 2009, and has seen good times and bad.
