It was just that I don't consider clearing the ball as winning the ball. Maguire cleared the ball to a corner which lead to the goal and two lost points last weekend. For me that is not winning the ball. Smalling made a huge amount of aerial clearances last season, most of them ended up at the opponent. Not winning the ball imo. In aerials also the offensive headers count, which is a not defensive actions, and not wining the ball as you already were in possession. You could basically win the offensive aerial duel but head it over the line, which is losing the ball. Those are some of reason why i do not consider it as winning the ball.
Both Bonucci and Laporte have pretty much the same figures as Lindelof and both are considered to be top CBs by most people.
Koulibaly had a great season 2017/18 despite 8.1 "defensive actions" per game. Yes, another top CB who had lower figures than Lindelof. On top of that Koulibaly was dribbled past the double amount compared to Lindelof and he also has many fouls, I think last year was 1.4 fouls per game compared to Lindelof's 0.6.
Personally, I don't think Lindelof will be one of the "best CBs of a decade", simply because at 25 he would already be top 10 if he were to develop into one of the absolute best. I can of course be wrong.
However, I think he can develop into one of the best CBs in the PL and maybe even Europe if he plays in a team that suits him. That is a criteria for most CBs, and most players, that they benefit from different systems. It looks like today's United is moving in a direction that is beneficial for Lindelof. I do not think his numbers of "defensive actions" are any problems, as almost all of the world's best CBs have similar numbers, with a few exceptions.
