Jurgen Klopp admits Darwin Nunez was deservedly sent off as the Liverpool striker was shown a red card for violent conduct in the 1-1 draw with Crystal Palace.
The Uruguay striker was making his full debut following his £64m move from Benfica in June but lasted less than an hour after aiming a head at Palace defender Joachim Andersen.
Klopp believes there was "provocation" for the incident but says Nunez, who becomes the first player under the German to be dismissed for violent conduct, can have no complaints as Liverpool face up to a three-game period without their big summer signing at a time when Roberto Firmino and Diogo Jota are also sidelined with injury issues.
