Sunderland boss Sam Allardyce was delighted with victory over Manchester United.

United started dreadfully at the Stadium of Light and fell behind to Wahbi Khazri's third-minute free-kick, which travelled across a crowded penalty area without anyone making contact and crept inside David de Gea's far post.

Anthony Martial's deft 39th-minute finish got them back on level terms - but they were second-best after the break and were undone when De Gea could only help defender Lamine Kone's powerful downward header into his own net.

Allardyce was thrilled with both his side's performance and the result as January signings Kone and Khazri in particular shone once again.

He said: "It was a really good performance today with the right result.

"Everybody that produced and played on that field deserves a lot of credit today for the way they have managed Manchester United and how often we have taken the game to them and created lots of chances to win this game - and finally got the goal that did win it from Lamine.

"Our new players have made a massive contribution since they have been here, but nothing bigger than today with Wahbi's goal from the free-kick and then his corner and Lamine scoring the winner for us.

"That hopefully will bode well for the rest of the season."
