The scrum-half feels head coach Matt O'Connor has added some real quality throughout the squad and he is looking forward to the start of the new campaign.
"It is sad to see guys come and go but we are certainly bulking the squad up for next year and it looks really exciting with the players who are coming in," Youngs told the Leicester Mercury.
"There are some back-row players coming in and Will Spencer in the second row has had an outstanding season at Worcester so I'm really optimistic about next season.
"There is no doubt the quality is there on paper it just about transferring it a lot more consistently on the field. I know once we get that right we will be a formidable side."
Youngs has not returned to Leicester for pre-season yet following his commitments with England.
