Gravenberch scored as Liverpool had a 2-0 lead at halftime, though Idrissa Gueye's goal had Everton fighting back in the second-half. However, Liverpool managed to hold on.
Gravenberch said afterwards: "Really happy. It's tough against Everton but we did really good and in the end got the three points so I am really happy.
"This one was quite tough. It was less time in between. Normally we play on the Sunday or in the evening but we recovered well. It's tough but we keep going."
"When they scored they came on more and more. We had the chance to score one more but if you don't do it they keep coming and we keep defending. We have a good defending line so it was still 2-1 and I am really happy with the three points.
"We had the opportunity to score more but 2-1, especially in this game, you have to defend. Next time we don't concede."
