He looks solid defensively. Anticipates trouble and clears it without slide tackles or having to be overly aggressive. It screams “I’ve got this under control” to me. Good timing, good anticipation, good tackling technique.
I have to admit that I absolutely abhor slide tackles, especially the fancy ones, as it typically means the player was caught out of position (not good for a CDM or CB) or has difficulty timing the tackle. It leaves the defender exposed if he doesn’t get the ball - beaten, yellow card, or free kick. Sometimes a good slide tackle is necessary, but all things being equal a highlight reel full of them is a red flag to me.
