He used to lose it carelessly. He doesn't anymore. There is a difference between ball retention and losing the ball on a dribble. If Pepe doesn't try and dribble he doesn't lose it. He also retains it under pressure.As much as we love Pepe and want to see him have a big season, no Arsenal fan can sit here and say he doesn't lose the ball carelessly. It happens all the time.
You are overcomplicating it with your team. It has no balance and no creativity. Its set up to counter attack, which we don't do.
It's weird how perceptions are different amongst the same fan base. I actually think Saka loses the ball more than Pepe.
