Virgil van Dijk has insisted his Liverpool team are not going to become complacent as they have returned to the top of the Premier League.

Liverpool beat arch-rivals Manchester United 3-1 on Sunday to reclaim top spot ahead of Manchester City.
The Reds travel down to Wolves on Friday evening, before games against Newcastle on Boxing Day and then Arsenal a few days later.
"We are in mid-December and the season is still too long," the Liverpool defender said to Sky Sports.
"We are very happy we're in the position that we are in right now but that can change in two or three weeks so we won't get carried away.
"We'll try to keep on doing what we're doing and, obviously, stay confident. It (Wolves) is another game we want to win.
"It's going to be very tough there. They are in a great moment but so are we so we will have to prepare well and know their strengths and their weaknesses as well."
Alisson made a mistake on Sunday, to gift Jesse Lingard an equaliser at Anfield, but van Dijk has revealed he has been joking around with his goalkeeper about the incident.
"I said to him 'We have no clean sheet because of you!' No, I made a joke out of it. He's been fantastic for us," van Dijk revealed.
"It happens, everyone makes mistakes. Maybe I didn't react as well as maybe I could have. It happens sometimes.
"It's how we react and he did brilliantly in the second-half. He didn't get nervous. We had to all bounce back and we did. I said to him, 'Just keep going, keep your head up and we'll be fine'."
