THE script was written, Callum Saunders comes off the bench to score a 90th minute winner with his first goal in professional football as Crewe moved out of the bottom four.

And for three glorious minutes for the Crewe Alexandra fans, that's exactly how it was played out.

The further sub plot was that the 20-year-old was booed by a section of the home fans when brought off the bench due to the fact his dad, Dean, left the club in January 2013 for Wolves with Doncaster top of League One and looking to make it back to the Championship.

But it was to another father, son act who was to have the final say.

As the clock ticked towards the 90th minute, the home fans began to sing, "It's Fergie time" in reference to their manager Darren Ferguson being son of former Manchester United boss Sir Alex whose teams were well known for their injury time exploits.

And that's exactly how it turned out here.

Saunders thought he had handed Crewe their third successive win, tapping home from close range after a well worked move, but Crewe were to not only slip back in to the relegation zone, but back to the bottom of the table as goals in the 93rd and 95th minute handed Rovers victory.

After the match there was understandably a real despondency in the Alex camp, but the mere fact they had dragged themselves clear from the relegation zone, even though it was merely for a few minutes, showed how far they have come in recent weeks following a nightmare start to the campaign.

Crewe Alex were dragged back to the bottom of League One when they conceded two heartbreaking goals deep into injury time at Doncaster on Saturday.

They thought they had strode away from the danger zone when Callum Saunders slid home his first ever senior goal to make it 2-1 on 90 minutes.

But strikes from Cameron Stewart and Andy Williams in added time snatched victory for Rovers.

It was a cruel lesson for the Railwaymen, who were good value for at least a draw. But they will know they should have stood strong and focused to seal a third straight win.

Doncaster Rovers scored twice in stoppage time to snatch victory from the jaws of defeat in a pre-Christmas cracker at the Keepmoat Stadium.

Callum Saunders - son of former Rovers boss Dean Saunders - thought he had won all three points for Crewe when he rounded off a fine team goal in the 90th minute to put his side 2-1 up.

But super sub Cameron Stewart curled home a delightful free kick before Andy Williams won it with a cool finish deep into stoppage time.
