Willo Flood thought Dundee United were due some decisions going their way in the 3-0 derby win in which he scored with a fortuitous late strike at Dens Park. United 's goals game from Keith Watson, Jon Daly and Flood but the latter admitted the scoreline flattered them. Watson dived to head home a 17th-minute corner against the run of play and United escaped a strong penalty claim when John Baird's cross came off the arm of Brian McLean after the defender had lost the flight of the ball. Referee Willie Collum awarded United a penalty in the 71stminute after Gary Irvine took down Stuart Armstrong after the midfielder had cut the ball back to Daly. United saw Rab Douglas save Daly's effort before the whistle blew for the penalty. Daly made no mistake from the spot to secure the three points before Flood's deflected late strike. Flood said: "It wasn't the best game we have played recently, or the most enjoyable, but the result was the most important thing. I think we got a few breaks but we were overdue a few breaks. We had two offside goals against Motherwell and Hibernian. We were due that, let's hope there's a bit more luck to come." Flood was not going to described his goal as anything other than a "shank" after his effort from 20 yards took a major deflection then bobbled over the arm of Douglas before trundling over the line. He added: "To be fair I was stretching for it. Richie Ryan wouldn't have been happy if it hadn't gone in, he wanted the ball - but I don't think Richie would have scored to be honest! I'll have a look at it on television and have a laugh and that will be it. It won't be sitting in the cupboard that's for sure." Dundee manager Barry Smith was frustrated with the referee penalty decision which in effect gave United two goal scoring opportunities. Smith, whose side are six points adrift at the bottom of the SPL, added: "The major decisions have gone against us. Up to that point in the second half we were probably in control and creating chances. They have won the game but did they deserve to win 3-0? I don't think so."
