I agree Malacia is a safe passer and press resistant himself, but only to sacrifice the team's progression as a tradeoff. For 60 minutes against Leeds, we totally relied on the Dalot/Sancho combination and Maguire's hopeful long balls to move the ball forward, while the left channel was non-existent. If you carefully look at the stats, Malacia's progressive passes and carries are significantly lower than his peers.
In terms of defending, he's good at marking the opponents tight and preventing them to turn, but nothing else. He's weak in dealing with long balls over the top and obviously, he struggles against opponents with physical presence.
I know my criticism may look a bit over for a youngster just landing in the PL, but so as the positivity here. I have actually revisited this thread a few times and every time I'm surprised the notion hasn't changed.
