Owen Coyle is hopeful that Stuart Holden will be available for the first day of pre-season training, while Lee Chung-yong continues to make strides towards a first-team return.
Holden is back in England after spending time in his native United States to recover from a serious knee injury that has kept him on the sidelines virtually all season.
The midfielder has been reluctant to give a definitive answer on when he might pull on a Bolton shirt again, and Coyle admits that is not likely to happen this term.
But the Trotters manager would like to think that Holden will be raring to go for the start of the 2011/12 campaign.
Lee could be back before the end of this season to help with Bolton's battle against relegation, but Coyle has reiterated that he will first need to play a couple of games for the reserves.
The South Korean has been out since breaking his leg in August in a pre-season friendly against Newport County.
"We are hoping that Stuart will be available for the first day of pre-season training, ready to make that impact that he already has again next year," Coyle said.
"Lee Chung-yong continues to get better - he has done some light training on the grass on his own.
"My hope would be - and he needs continued improvement for this - that he can join in my training with the group in a couple of weeks' time.
"Then, if that is the case, we would need a couple of reserve games and I'd be hopeful that he might be able to be involved before the end of the season."
