Boro manager Tony Pulis says the narrow loss to Norwich City was a tough one to take for his side.
Onel Hernandez broke the deadlock for the Canaries inside the first ten minutes of second-half action.
After a number of unconverted chances in the first period, Pulis was frustrated at his side not being clinical in the final third.
“Again it’s pretty hard to take,” he said.
“First half we had some good chances to score, but they’re a good side, they’re good on the break and they caught us a few times.
“Dani (Ayala) hits the post just before they score and if we score, that gives us a lift. They scored the goal and we dropped our heads for 20 minutes again, and we can’t afford to do that and they play some good stuff.
“We came back into it, we had three, great opportunities to score and, again, we have to score goals.”
