South Korean midfielder Kim Bo-kyung's dramatic stoppage-time equaliser earned Cardiff City a 2-2 draw that prevented Manchester United from climbing into the Premier League's top four on Sunday.
.
United, who had seen Wayne Rooney controversially escape a red card, were on course for the Champions League places until Kim stole in to head home a Peter Whittingham free-kick in the 91st minute.
.
Surprise 3-2 victors over Manchester City earlier in the season, Cardiff inched three points clear of the bottom three thanks to Kim's goal, while United were left in sixth place, seven points behind leaders Arsenal.
.
"There's just disappointment that we didn't take all three points in the end," United manager David Moyes told Sky Sports.
.
"But Cardiff made a game of it and put us under some pressure. We gave away a stupid free-kick that led to the goal."
.
Moyes disagreed that Rooney was fortunate to avoid being sent off after angrily kicking out at Cardiff's Jordon Mutch, saying: "I didn't think it deserved any more than a yellow card."
.
Rooney lashed out after Mutch ran across his path in the early stages of the game in the Welsh capital, but referee Neil Swarbrick only showed him a yellow card and in the 15th minute the England striker put United ahead.
.
Antonio Valencia's right-wing centre was flicked on by Javier Hernandez to Rooney, who turned inside and let fly with a shot that beat goalkeeper David Marshall via a deflection off Gary Medel. Cardiff's fans were furious that Rooney had been allowed to stay on the pitch, but they saw their side draw level in the 33rd minute with a beautifully constructed goal.
.
Medel found Whittingham, who helped the ball on to Mutch, and he released former United striker Fraizer Campbell to beat goalkeeper David de Gea with a first-time finish.
That was a very painful equaliser for all Manchester United fans
