Kone struck the winner against Norwich City on Saturday.
"Heâ€™s come into great form at the right time of the season, just when we needed him to," said Wigan captain Boyce, following the 29-year-oldâ€™s 10th Premier League goal of the campaign. "Heâ€™s our strike weapon, and heâ€™s on fire at the moment.
"We were pressing hard, and we deserved this win. Thatâ€™s not luck â€” itâ€™s down to spirit and determination.
"And when youâ€™re in this sort of situation what you need most is someone who can score crucial goals, and weâ€™ve got that in Arouna. Getting into double figures in this league is no mean feat."
