He looked fine last season at least.
Kepa seems to have zero connection with Zouma and Tomori, he constantly anticipates those players to move to different positions than where they are actually going. Watching the 3rd goal, it does look like Kepa is assuming Zouma continues moving forward as you would expect from a player whose team is chasing the game. But because Zouma is standing completely still the pass looks like it's overhit and Everton players manages to intercept it. He hardly had any communication issues like this with Luiz and Rudiger and we overall were far better in these positions last season.
I'm not worried about Kepa's passing in the long-run, it's the weak wrists that need the most work.
