Disappointed defender Will Boyle admitted the Robins had to learn the painful lessons after a heavy 6-1 home defeat to Coventry City at the LCI Rail Stadium.
Boyle conceded the manner of the loss to play-off chasing Coventry had been one of his hardest days in football.
But he insisted there was no time to mope after the result and improvements and to be made.
"They were very good and we were very bad. It's hugely disappointing,” admitted Boyle.
"We can't mope around, we've got next week and we've got to take from it what we can, learn the lessons and look to improve to spur us on for next year.
"You can say they were good goals they scored, but you've got to analyse yourself and be critical of your own game and see where you could do better. That is the way I will look at it.
"Early on in the season we tended to concede goals in bunches and obviously we have done that again the last two games.
"Teams have got on top of us and made it count. As a team we have got to look at it and work in it.”
The Robins now travel to Crewe next weekend and Boyle admitted victory was vital ahead of the summer.
"It's definitely a good thing we have got another game,” he added. “I remember when we got beat on the last day of last season at Portsmouth and it left a bitter taste in the mouth all summer.
"We can’t let that happen next week and hopefully we can put a bright spark on the end of the season.”
