Manchester United manager Ole Gunnar Solskjaer was delighted with his side in Sunday's thrilling 3-3 draw with Sheffield United.
The Red Devils scored three goals in seven minutes to overturn a 2-0 deficit with ten minutes remaining.
John Fleck and Lys Mousset had the hosts ahead after 52 minutes.
But a rush of goals from Brandon Williams, Mason Greenwood and Marcus Rashford had the visitors jumping, only for Oli McBurnie to equalise on the 90th minute mark.
"Sometimes football is beyond tactics," Solskjaer told Sky Sports . "The energy compared to ours in the first half and then we get that goal and we start to believe.
"The difference in the team this year compared to last is huge. They never give in.
"Last year we would have gone four or five down instead of coming back. We would not have been able to come back."
