So according to OP, Matic is the best choice with what he had.
Kidding.
= Mctominay.
There are plenty more arts in defending, not just tackling, interceptions, not letting players dribble through and fouls related.
Listing just the sort of 4 ways there is too limited.
Few others ways eg. pressing well so much so the opposite player had to pass back or away, good coverings when your teammates made mistakes defensively, good heavy markings to unsettle players, hold your ground well which prompt the players to not even try dribbling, etc are the other things which McT did better. He also didn't make pointless fouls, just the necessary fouls. Aerially he's also good, not letting successive long balls.
And I think we should give credits to Pogba's real abilities. The popular notion is he's bad at defending. I completely disagree with that.
