Van Dijk plays next to a CB who makes a good amount of attempts at winning the ball
This means his defensive partner is being far more aggressive while VVD isnt a very aggressive CB. Thats why it works.
On top of that there are areas where VVD is strong with his defending
So he makes a healthy number of clearances, a good amount of headers and a high success rate from them. He's still less of a ball winner than some of his partners, but one of the CBs is doing what he's not.
Now lets look at United
Every single Liverpool CB other than VVD attempts to win a tackle more often than United's CBs.
Every Liverpool CB makes more interceptions than Lindelof including VVD. Maguire makes more than Liverpool's CBs.
So Lindelof is the only one who both attempts very few tackles, and very few interceptions. Lindelof makes the fewest combined tackles and interceptions of all United and Liverpool's CBs this season other than Rojo who played 1 game.
Now we go onto the part where VVD has his strengths in defending
So Gomez is the only CB who played more than 1 match who makes less clearances per 90 minutes than Lindelof
Lindelof attempts less headers than any Liverpool CB, but with Shaw and one game Rojo attempting even less than him.
So in summary with all the proof above - Yes you can make a comparison to VVD when it comes to not engaging in making many attempts to tackle. But VVD does engage and try to intercept which Lindelof does not. Thats a non-aggressive side to VVD thats balanced out by his CB partner trying to make more tackles and interceptions.
BUT the difference is that VVD has his strengths with defending too - makes a good amount of clearances, and a high amount of attempts at winning the ball in the air with a good success rate.
Lindelof has the non-aggressive side down with a similar amount of attempted tackles, but doesnt play next to a partner who does attempt to get in a tackle unlike VVD. Lindelof also attempts to intercept less than VVD, but Maguire does intercept more than Liverpool's CBs so that one part is covered.
Unlike VVD, Lindelof doesnt make many clearances and doesnt attempt many aerial challenges. So essentially he has the weaker part of VVD's game where someone else helps him out being more aggressive trying to win the ball, but he also has weaknesses in the areas where VVD excels. So theres no pay off unlike VVD. He's just low on everything.
Maguire on the other hand is just a little under VVD's numbers in those strong parts of his game, clearances and aerial challenges though with a worse success rate.
So now Maguire has Lindelof covered with interceptions, clearances and aerials. While together the two lack in attempted tackles.
Maguire does all the work and Lindelof has no strength in defending. Thats the problem.
