Under Grant two years ago Chelsea won all their games during the Cup, though they did drop two points at Fratton Park in early February with a team missing all four Africans.
"At the beginning of November all the newspapers began to ask me how many players I would buy in January," said Grant to the Observer. "I decided from day one I would trust the squad and we won nine in a row, a record.
"But it's not just the Cup, you have a problem after because players come back and take one or two weeks to get used to the conditions again. Africa is very hot in January, England very cold."
Is January a good time to buy?
"Generally in the big teams I don't think they need to because at the beginning of the season you prepare for injury, for everything."
