Centrebacks shouldn't need to tackle that often. It's about reading and positioning and intercepting more than anything. Your sitting mid should be the monster tackler (5+ successful challenges per game) and well...
I've seen him get criticism for Benzema's 2nd goal, and I don't buy it. He makes the probabilistically correct play at every turn, but he's just caught between a rock and a hard place (letting Vinny Jr a direct run at goal vs leaving some recovery for Benzema), then it's perfectly okay to go back on the line and not expect three of your teammates to completely buy the dummy.
