It can't be understated the winning mentality Van Dijk has brought to us. Since he has came in we have won trophies or hit the bar with them. You can see in games he demands a high level from the lads, if he is like that on a daily basis, demanding high standards, its no wonder.
You dont get many players like him in football. A lot of players demand a lot, but they dont have the aura or personality about them, or the quality and consistency to be able to get it. Big man has the lot, and he has a taste for it
