Late on Thursday afternoon, after Liverpool's training session at Melwood had ended, Gini Wijnaldum climbed aboard the private plane he had paid for to whisk him to Holland for the evening.
It was not so he could attend a rock concert or party the night away in a club in Amsterdam. That is not really his style. It was because he wanted to repay a debt of sorts.
Six years ago, during an unhappy period in his time at PSV Eindhoven when Wijnaldum was being left out of the side and his critics were saying he had failed to live up to his early promise, Willem van Hanegem, one of the great Netherlands players of the Seventies, wrote an article about him in a Dutch newspaper.
