Boss Bryan Robson had mixed feelings following Tuesday night's six goal thriller against Cardiff City at Bramall Lane.

Chris Morgan's injury-time header from David Carney's corner in front of the Kop salvaged a point for the Blades in a game which looked like bringing them nothing - despite an excellent first-half showing.

Robson commented, "It is disappointing because I felt we did enough to take all three points. The first-half performance was probably the best since I arrived at the club, we could have had three or four goals by half-time.

"The attitude of the players was very good and I couldn't believe we went into the break behind."

More defensive frailties and a dubious penalty decision saw United trail 3-1 after an hour, after James Beattie's 8th of the season gave the home side an early lead.

Robson admitted, "We didn't track the runners for the first goal and having looked at the video it didn't look like a penalty - Chris Morgan has blocked the ball against the lad's legs."
