Darren Ferguson acknowledged that defeat to Crewe has sealed Doncaster Rovers’ relegation fate - and said the 3-1 reverse summed up their season.
Rovers led through Tommy Rowe’s third goal in three games.
But they conceded a horrendous equaliser on the stroke of half time after defender Cedric Evina completely switched off and allowed Callum Ainley to equalise.
The Railwaymen scored twice more in the second half to leave Rovers all but mathematically relegated.
“It’s a terrible day for the football club to be relegated into League Two,” said Ferguson.
“It’s been a teribble season.
“You’re not making 12 goals up. Of course, it’s still mathematically possible but you know your own fate.
“Today in many ways summed up what I feel has been our problem; the small things that happen in games affect us too much. It’s been a consistent thing for me. We’ve not been strong enough mentally to cope with things that go against us within games and over a period of time.
“We were in complete control of the game. We should be more than 1-0 up, we make a mistake and it’s one-all, and I think that affected us too much when it shouldn’t have. It was a really small matter and we still had 45 minutes to win the game.
“That’s been the stand-out for me if you were to ask where the problems have been. Mentally we’ve not been strong enough to cope with adverse situations.
“I’ve said to my players I can’t come out when I speak to you guys [the press] or when I’m speaking to the fans and make any excuses. There’s none that I can make. It’s just simply been nowhere near good enough.
“I’ve got to learn from certain things that have happened this season and I’ve got to be ready to go again next season, which I will be.”
