Gini Wijnaldum says Liverpool must learn from their shock defeat at Watford.
The Reds had gone 44 Premier League games unbeaten prior to the loss, having not lost in the competition since January last year.
Posting on Instagram after the defeat, Wijnaldum said: "Tough losses should be an opportunity to improve.
"Time to regroup and give it our all in the very next opportunity we get."
In a separate post on his Instagram story, Wijnaldum added: "When you don't win, make sure you learn."
