Danny Wilson says Tuesday's six-goal thriller at the Lane was ideal for the neutrals but a nightmare for both managers.
United led 2-0 after 30 minutes, with Shaun Miller and Harry Maguire on target, before Crewe scored three times in the space of a mad five-minute spell either side of half-time. Nick Blackman was the man to rescue a point for the Blades with his 10th of the seaon.
Speaking afterwards, Wilson said: "It was a nerve-racking game and when you see certain inconsistencies in the performance you know you are going to have problems.
"We have both (teams) got away with a 3-3 draw and we both have to accept the point. We aren't happy with aspects of our game because we are better than that.
"It was so open, one minute we looked like winning it, the next we could have lost it. It was a fantastic game for the neutral, but plenty for us to dissect and work on.
"We made a few poor decisions defensively and they cost us, but in time they will be rectified.
"We always want to win our home games, of course we do, but when the dust settles we will take the point and move to Brentford where we are confident of getting a result."
The Gaffer was frustrated United weren't awarded a penalty in the second-half, but is refusing to get too despondent after the stalemate:
"We feel it was a penalty, and after seeing the DVD we feel those claims are even stronger, but the referee saw it differently.
"It must be a learning curve for the youngsters, but we certainly won't go round pointing the finger because it is the first time we have looked so fragile defensively.
"We have to remain positive, we have got four points from the last two games and although we would have liked a maximum six we aren't going to get downbeat.
"If people want entertainment, they certainly got us, unfortunately we didn't win the game which is disappointing, but thankfully we haven't lost."
