Former Arsenal manager Arsene Wenger says Liverpool's greatest strength is the players' "intelligence".

The Reds are on track to go through this Premier League season unbeaten.

Wenger said, "They play intelligent football, their players make intelligent decisions on the pitch.

“That is very difficult to get in the team because you need a special run to do that and to get the fear of losing out of the team.

“It's something that is very important and they have that at the moment."
