Blues coach Sir John Kirwan says that he believes his Super Rugby team have plenty of maturing to do as professional rugby players.
The Blues 34-13 loss in Bloemfontein means that they can no longer reach the play offs and they will be playing the Chiefs this weekend for pride alone.
Kirwan who is coming to the end of his first year in charge of the Blues says that they need to learn how to close out games.
"I think the most disappointing, reflecting now, was the Highlanders, where we just weren't professional enough to go down there and really do the job.
"And I think that's got a lot to do with young guys learning to be very good professionals," Kirwan told Newstalkzb.
The Blues allowed the Cheetahs to build up an early lead and by half time the Blues were trailing 19-10 and Kirwan says that they need to mature as footballers.
"It's a bit of a reality check for us, we know how we can play."
"We've got the ability, although the side's very, very young, but I just think they just need to learn about preparation."
The Cheetahs victory over the Blues secured them their first ever place in the Super Rugby play offs.
