Doncaster boss Brian Flynn believes his side's fightback in a 2-1 win at Crewe could prove to be "pivotal" in the npower League One leaders' season.
Former Port Vale striker Billy Paynter's double completed a quick-fire comeback for Doncaster, who stay two points ahead at the top of the table.
Max Clayton had fired Crewe ahead, but Paynter came off the bench and netted twice in four minutes to ensure Rovers stayed in pole position.
Oliver Turton blew a late chance to earn the Alex a draw they arguably deserved as Crewe suffered their second defeat in a week since lifting the Johnstone's Paint Trophy.
Flynn said: "Once again we have bounced back from defeat and it could prove a pivotal result. It was probably our least effective performance for about three months.
"The second half was littered with mistakes, but what we showed was desire and a willingness to get back into the game and that has become a characteristic of this team. We are excited now, but we can't ask favours from anyone else. If we take maximum points from the last few games we get promoted."
Alex boss Steve Davis could only wonder at the resources Flynn has at his disposal.
Davis said: "Billy Paynter made a big impact. He is a goalscorer and has played at a higher level. That is what teams have a big budget for so they can afford players like that who can come and make an impact for you off the bench.
"They were a big, strong forceful team and that is what seems to get you to the top of this league. I wouldn't want to play that way, we are always going to try and get it down and play."
Alex broke the deadlock in the 54th minute.
