He was never very good with the ball at his feet but he looked a lot less bad because 7 or 8 years ago there much less expectations on keepers to be comfortable on the ball.
He was always able to hit an accurate long pass out wide and can still pull this off, given enough space and time. What he never did was to look like an extra defender when we’re passing the ball round the back. At ease on the ball, making and receiving passes on either foot, instantly aware of the best passing option and relaxed when getting closed down. That’s the expectation from top keepers now and he’s being shown up by far better ball players in goals at other clubs.
At first I thought that it was reasonable(outside of the fact that I didn't suggest that he was very good ). But 7-8 years ago, is the era where the goal is to have players that are ideally like Neuer or Ter Stegen but more realistically like Bravo, Navas or Buffon. The exception among top teams and goalkeepers was Oblak and to some extent De Gea.
