Ole Gunnar Solskjaer felt Manchester United proved a point about their battling qualities after a stirring fightback in a 2-2 draw against Burnley at Old Trafford.
Solskjaer had overseen eight consecutive victories since taking interim charge last month although the honeymoon period looked to be coming to an end when Ashley Barnes and Chris Wood gave the Clarets a shock 2-0 lead.
It was the first time United had trailed under Solskjaer but his unbeaten record would remain in tact as Paul Pogba's 87th-minute penalty and Victor's Lindelof's strike in time added-on rescued a 2-2 draw.
The Norwegian was not entirely satisfied with the stalemate but said: "The way they came back was fantastic, so of course you're happy with the point.
"Then again we could have got three. We just ran out of time towards the end and we started too late with the urgency that we needed, that's a learning curve.
"But now you've got your answer: can they come back if they go one or two down? I'm very happy with the response."
United lacked the usual sparkle that has been a hallmark of the Solskjaer era so far, which was not lost on the former United striker, who made five changes to the team that overcame Arsenal in the FA Cup last Friday.
Solskjaer suggested their red-hot form under his stewardship might have had a negative impact on their mentality ahead of their fixture with Tuesday night's opponents.
"In the second half at times I thought we did fantastic in that respect but Tom (Heaton) is a good keeper and they headed the ball away when we crossed it. But we found a way in the end."
United's evening ended on a possible sour note as midfielder Pogba was seen limping through the mixed zone after appearing to take a knock.
Burnley boss Sean Dyche was left puzzled by the five minutes of time added on and thought the announcement vitalised a crowd accustomed to late goals and thrilling finishes under Sir Alex Ferguson.
Victor Lindelof struck in the second minute of time added on – a goal that Dyche believes should have been chalked off for offside in the build-up.
Dyche said: "I have no clue where a mystery five minutes came from, I don't think anyone in the stadium did, everyone in the stadium had a gasp as to where the five minutes has come from.
"Every minute counts at that stage of the game, you see what happened and how late the goals are. In these parts for the history of this club, when five minutes goes up, everyone believes.
"I asked the officials and they didn't give me a very valid reason. They seemed to come from somewhere.
"And then if you look at the margins, I think you'll find when (Alexis) Sanchez wins the header, Lindelof is marginally offside and, as it comes off the keeper, he finishes it. That's a nice debate for everyone, at least."
