Manchester United boss Ole Gunnar Solskjaer found positives after their 4-1 defeat at Watford.
Solskjaer was happy with goalscorer Donny van de Beek and fellow substitute Anthony Martial at the final whistle.
He said: "Both of them, Anto [Martial] and Donny [van de Beek] played really well. That's the irony of it. In the second half, we played some fantastic stuff, created four or five big chances, Ben [Foster] had a couple of decent saves, we had a few more.
"But then of course it's hard in the last 15 minutes playing with 10 men but I still thought we gave it a go second half and just couldn't get the second goal that might have got us a point."
Solskjaer also said: "We started too late. We started at half-time. The second half was very good. In the first half we never turned up. They outfought us, we allowed them to get the ball in the box, we allowed them space.
"They won most of the challenges. And then you get to 40 minutes 1-0 down and you're probably lucky to be 1-0 down, David made two fantastic saves from penalties and there were some blocks. But then that second goal came in.
"From half-time, the response was very good. I thought we played really well for half an hour until we ran out of legs. But it was nowhere near good enough of course. I'm not going to say anything but that."
