United showed real resolve to battle back on three occasions to force a 3-3 draw with Bolton thanks to goals from Jack Rudge, Sam Byrne and Luke Hendrie.
The youngsters' frustrating habit of conceding very early goals this term continued when Rudge tripped Luke Woodland with his right leg inside the box after only 30 seconds. James Caton comfortably beat Liam Jacob from the spot to hand the visitors the perfect start.
Again as has often been the case this season, Paul McGuinness' side responded positively and were back on level terms following an Adnan Januzaj corner. Lewis Fielding could only parry into Rudge's path and the midfielder atoned for conceding the penalty by drilling home.
Bolton restored their lead against the run of play when Zach Clough released Chris Lester and his assured right-footed finish gave Jacob no chance. Mats Daehli rattled the woodwork and, just before the break, United were back on level terms when the Norwegian midfielder fed Hendrie and the full-back's excellent cross allowed Byrne to glance in a header via an upright.
Fielding had problems dealing with a deflected Gyliano van Velzen shot when colliding with his left-hand post and dropping the ball as the Reds pressed after the interval. However, the Trotters took the lead for the third time when a wind-assisted free-kick by Glenn Matthews was palmed into his own net by Jacob.
Jack Barmby could only scoop his shot over the bar following a Januzaj cross from the left and then bent another attempt off target after an immediate impact from substitute Donald Love.
But the pressure told when Love fizzed a dangerous ball across and Hendrie was on hand to tap in a third equaliser. Substitute Kenji Gorre had the best chance for a winner but shot just wide.
United: Jacob; Hendrie, Blackett, McCullough, Ekangamene; Barmby (Gorre 79), Rudge (Love 73), Daehli, Januzaj, van Velzen; Byrne. Subs not used: Rowley, Sutherland, Wilkinson.
