Van Dijk knows how important it is to get their Champions League group stage campaign back on track as quickly as possible, adding: “It can definitely change.
“There are so many games left to play but you wanted to start well. The situation is what it is.”
“The next game in the Champions League is Ajax at home and we need the fans, we need a good performance from us.
“Obviously it starts on Saturday with a good opportunity and against a good team, so we’ll give it everything. Like I said, the key is to be together. We need everyone.”
“If you start blaming others and don’t look at yourself or create negativity around the club, then you won’t get out of it. I’m fully confident that together we will turn it around.”
