Definitely (mainly) at fault for both goals IMO.
First one - should have passed it first-time to Matic, taking a touch there is always disastrous. I will mention Maguire as captain needs to be more responsible there though, ideally turn and play it out-wide to Telles, or if you're going to play it back be less casual about it and play it to Henderson's right and tell him to punt it - he played it straight in to his feet and the young 'keeper takes a touch to try and open up his body so he can play it out.
Second one - should have committed and come for it as it was well within his 6-yard box. He started and then changed his mind and by the time the ball had ricocheted off McGoldrick, he was backpedalling towards his line and therefore completely rooted to the spot. A mention here though - seemed like he was asking for somebody on the post, which would have led to that being cleared off the line if the defence had listened to him.
Good save at the end to preserve the 3 points, but overall a bad performance. As a previous poster said, unfortunately his flaws are exactly the same as De Gea's - lacks composure with the ball at his feet and doesn't appear to command his area very well. Doesn't really give you an 'alternative' option to De Gea per se as they are pretty much the same, it's really just a like-for-like swap IMO.
Great shot-stopper and still might be my pick for #1 for United based the fact that De Gea makes a lot of mistakes now in that regard letting in efforts he should save, but I fear that Henderson might never fix the aforementioned issues and therefore United long-term might need a 'new keeper who fits the modern mould.
