Blackpool's Tangerine dream was shattered by one of those famous Manchester United comebacks as they roared back from two goals down to win 3-2.
Craig Cathcart rose unchallenged and powered a header past a motionless Edwin van der Sar to break the deadlock.
Elliot Grandin scooped a 12-yard effort over the bar and David Vaughan brought an excellent save out of Van der Sar, which as it turned out, only staved off Blackpool's second by half a minute. Another Charlie Adam corner saw Darron Gibson got his head to it but he only succeeded in turning it to DJ Campbell, who bundled home at the far post.
If Luke Varney had been granted the penalty he was convinced should have been awarded when Rafael sent him tumbling, Blackpool would almost certainly have won.
Dimitar Berbatov was on hand to tap United back into the contest and within two minutes they had bagged another as Ryan Giggs' magnificent chip sent Javier Hernandez streaking through to finish.
Even the departure of Rafael on a stretcher that required 10 minutes injury time failed to halt their momentum. And when Paul Scholes sprayed a magical pass to Berbatov, the Bulgarian blasted home his fifth goal in four days.
