Despite Swindon already confirming a play off spot with a 3-0 win over Stevenage, the Robins are set to field a full strength side at Glanford Park.
"As well as the youngers have done, they are not ready to start games", he said.
"It wouldnt be very nice for Colchester if we started with 5 or 6 youngsters.
"We have to do things right.
"If Scunthorpe beat us they beat us but we have to do things right."
Tommy Miller and Alan Navarro may return to the matchday squad for the Robins, however Simon Ferry will definitely miss out through injury.
“Alan (Navarro) only trained with the physio today and he hasn’t joined in any football. This was Tommy’s (Miller) first day of joining in with the football. Simon Ferry will not be available for this weekend but we’re hopeful that next week he will be", he added.
