Ghana will go 4-3-3 against Mali later on Tuesday when they clash in a friendly international in Paris.
The game in France comes after the Stars lost 2-1 defeat to Senegal on Saturday.
In his quest to make Ghana look pliable, Grant will try a more wing-based approach after going with a traditional 4-4-2 in Le Havre.
“It's a different target now to when in a tournament,” Grant said.
“In friendly matches, you have a chance to try different situations and different systems...we will start with the 4-3-3 and see how it goes.”
In Equatorial Guinea, the Stars mixed a fast-paced style centred on wingplay with the more traditional role.
