Liverpool striker Darwin Nunez lost his head and was shown a red card for headbutting Crystal Palace centre-back Joachim Andersen on his home Premier League debut for the Reds.
The Uruguayan striker, 23, was grabbed by Palace defender Andersen and reacted by headbutting the Dane, giving referee Paul Tierney little choice but to brandish a straight red card for his recklessness in the 57th minute. Andersen was floored by the headbutt.
Frustration had been growing having gone behind to Wilfried Zaha's 32nd-minute goal against the run of play, but Nunez's reaction to being provoked beggared belief. The dismissal will see Nunez suspended for next Monday's trip to Old Trafford.
