Blues go top of the Magners League on points difference but Young insists drastic improvement is needed ahead of their Heineken Cup campaign opener against Edinburgh next week.
"The major positive is that it was a win but I think we all realise that it wasn't the performance we were looking for," said Young.
"It was our poorest of the year, but, if anything, maybe that's good for next week.
"Certainly, it will make us keep our feet on the ground and give us a lot of determination to work on things for next week.
"I didn't think we were ever going to lose against Connacht because they didn't cause us many problems, but it goes without saying we are going to have to play better when Edinburgh come to us in the Heineken Cup."
