Sunderland manager Martin O'Neill has admitted that he is "thrilled" with his side's 1-0 victory at Southampton in the Premier League.

The Black Cats earned a vital three points against their fellow strugglers on Saturday thanks to Steven Fletcher's eighth goal of the season.

"It was a big performance from us today, and I am thrilled not only for the team but also the fans who have travelled down today," O'Neill told BBC Sport.

"[Fletcher] has been fantastic and at times I think we are struggling to keep up with him."

The win has moved Sunderland up to 15th place in the table.
