The Englishman lost his job with the Porcupine Warriors last month following their preliminary round elimination from the Caf Confederation Cup.
He joined the side in May last year, his spell lasting only nine months.
“I’m a bit sad that I’m leaving," Polack told Citi FM.
"I feel like, I need to go home, have a little break; get refreshed mentally and physically, spend some time with my family and who knows I could be back here in a couple of weeks’ time.
“But if I was to come back to Ghana, It has to be a club that actually has a vision and plan, and a strategy for one, two, three-four-five seasons and they are ambitious. Not like hey! We got to win today otherwise you are out."
Polack, who led Kotoko to win the Ghana FA Cup last season, has never hidden his disappointment about the manner at which he was fired.
His grievances are so apparent in his reply, when asked whether Kotoko's decision showed their lack of vision.
“Well, let’s just say, I don’t know what the planning order is, so you need to ask them what the plan is," the 57-year-old said.
"I don’t know what the plan is…”
Before joining Kotoko, Polack had stints with local sides Berekum Chelsea and King Faisal Babes.
