Cork has done very well during his loan spell at Glanford Park this term, making 30 starts and two substitute appearances and scoring two goals.
But the 18-year-old, son of former Wimbledon striker Alan, faces an uncertain future when he returns to Stamford Bridge.
"When my loan finishes here I'll go back to Chelsea and I think there will be some tournaments for me to play in for the Under 19s.
"I want to see what happens in pre-season. Breaking into the first team would be the best situation, but you don't see many players coming through into Chelsea's first team as there's a lot of pressure on the manager to keep winning.
"This loan spell has really helped me, both mentally and physically. I'm doing a lot of stuff with John (Noonan, the club's strength and conditioning coach) in the gym. It's really helped me as a person and a footballer.
"I've also had the chance to play against some big players like Jimmy Floyd Hasselbaink - I used to see him play when I was a ball boy at Chelsea, so to play against him was quite a big thing for me."
