Michael Carrick conceded Manchester United were "definitely not at our best" but hailed the fighting spirit to salvage a point against West Ham.
United have won each of their last four games before heading to London Stadium, but instead, came close to suffering their first defeat since Carrick returned to the club.
However, Benjamin Sesko struck a 96th-minute equaliser to cancel out Tomas Soucek's earlier goal to earn a 1-1 draw for United, extending their unbeaten streak to nine league games and ensuring they remain in the top four.
The Red Devils had just nine shots against West Ham, worth 0.6 expected goals (xG). It is only the second time this season they have had fewer than 10 attempts in a Premier League match (five versus Tottenham in November).
And Carrick admitted the quality was lacking in the final third as they struggled to break West Ham down.
"We were ok. I think we were a little disappointed, and we were definitely not at our best," he told TNT Sports.
"It's times like that when you find a way and move on. I'm a little frustrated at that. It is a tough place to come, and we didn't have that sharpness to find the answers.
"Great spirit again, and we will take the point and move on.
"For where we are and being together for a short space of time. In the end, we have took a point. It didn't come easy, and we found a way to take a point. We will take some positives from it."
Defensively, United have struggled on the road, having conceded at least once in each of their last 18 away league games, their longest run without a clean sheet since September 1970 and September 1971 (25 matches).
However, at the other end, Sesko got another late result-altering goal, having also netted a last-gasp winner against Fulham on February 1.
After scoring just two goals in his first 16 Premier League appearances, Sesko has since scored four in his last five.
"It is not surprising; that is what Ben has got in him," Carrick told BBC Match of the Day about Sesko.
"He is dangerous in and around the box. That's two really important goals for him – one to get a point and the other to get a win. Delighted for him."
