He's not great, arguably not even good, at them. Yet what does that tell you when he's still significantly better than De Gea?
I also tend to think some of it was him trying too hard to show what he could do, same with a couple of the times he came charging out of the box to clear a ball that he perhaps shouldn't have. I really got the feeling he was trying too hard to show that he could do all the things that De Gea refuses to do, and with more game-time and trust put into him I would hope that he'd settle down a little. But even if he didn't and he stayed as risky in those moments as he was last season, I'd still prefer him at that level than De Gea's complete incompetence.
