Fans slammed both van Dijk and Liverpool goalkeeper Alisson for failing to deal with a ball, letting it bounce, and gifting Martinelli the opportunity to regain Arsenal’s lead in the match from 18 yards.
But in his post-match interview, Liverpool captain van Dijk admitted he takes the blame for that crucial second goal.
Van Dijk told Sky Sports it was ‘a tough day’, adding: ‘I think the 2-1 [Martinelli’s goal], I take full responsibility for that.
‘That is a big moment in the game. I should have made a better decision — it hurts for me.
‘The turning point is my responsibility, I should try to clear it. Obviously these things don’t happen too often in my career, but I will recover from this.
‘It is a physical game and I am not looking for excuses. At the highest level it is a split decision.
‘Alisson touched me a little bit and he couldn’t clear it, but I take full responsibility for this and I will try to make sure this doesn’t happen again.
‘It hurts losing. The way we did it today and in so many ways it was unnecessary.
‘It hurts for me and seeing the fans coming all the way down and the whole club it is not nice to be involved in mistakes, but I will work hard and be back.’
Fans on social media were quick to blame both the captain and the goalkeeper for their mistakes in allowing Martinelli to score.
