The 20 year-old, who finished with 18 goals for the campaign and still has a year to run on his contract, is yet to open talks about extending a deal despite Robins speaking with his agent a month ago.
"We'll see what happens. I'm fully expecting him to walk through the door when we returning for pre-season training, but you never know", said the Rotherham boss.
Enquiries have already been made about Reid's availability as Rotherham attemopt to pin him down to a longer term deal.
Meanwhile Robins himself has again been linked with a move to former club Norwich City as they were relegated from the Championship over the weekend.
