Werder Bremen and Hannover shared six goals at the Weserstadion on Saturday in a northern Germany derby which ended all square.
Lars Stindl gave visiting Hannover the lead in the 12th minute, but a Zlatko Junuzovic free-kick levelled matters before the break.
Melvyn Lorenzen scored his first professional goal to put Bremen in front, but two goals in as many minutes from Joselu turned the game on its head before teenager Davie Selke grabbed a late equaliser to salvage a 3-3 draw for the home side.
Hannover got the first goal of Saturday's Bundesliga action, crowning a bright opening for Tayfun Korkut's men at the Weserstadion.
Stindl poked the ball in at the far post after Bremen's defence had been led a merry dance by Hannover's forwards.
Bremen almost levelled seven minutes later when Junuzovic curled his free-kick against the post before Stindl wasted a glorious opportunity to double the away side's lead, forcing Richard Strebinger to make a save.
Junuzovic's brought Bremen level with a perfectly struck free-kick in the 35th minute, curling his effort over the wall into the top left-hand corner, only moments after Stindl's header was cleared off the line by Felix Kroos.
Goal-line technology would have been needed to clear up whether the ball had crossed the line or not on that occasion, but the German Football League will not be introducing that until the start of next season.
Lorenzen was introduced by Bremen coach Viktor Skripnik on Saturday, but he will not be needing any more introduction in future after the goal he scored to put his side in front.
The 20-year-old picked up the ball down the left wing and he cut inside, beating two defenders before picking his spot in the far corner of Ron-Robert Zieler's goal.
Hannover hit back with Hiroshi Kiyotake racing to the goal line to reach a long ball before it went out, and he laid it on a plate for Joselu to level from close range.
Joselu struck again within two minutes, although this time he had luck on his side as he touched Kiyotake's free-kick past Strebinger from a clear offside position.
It would have been a cruel way to lose the game, but Bremen boss Skripnik had another young player up his sleeve - 19-year-old Selke.
A dead leg meant he was unable to start the game, but he came on to score an equaliser in the 88th minute from Alejandro Galvez's pass.
