Mandjou, who moved to the Sultan Mohammad IV Stadium late last year, was finally registered for the Malaysia Super League this season following the departure of Lebanon international Mohammed Ghaddar.
Despite being a real hit in his last stint in Malaysia with Perak, netting 50 goals in 75 games and finishing as the league's top scorer in both the 2005/06 and 2006/07 seasons, the Guinea international has failed to fire for the Red Giants, leading to speculation he could be replaced when the transfer window opens in April.
However, he did himself a huge favour earlier in the week for he finally opened his Kelantan account to help them down their East Coast derby rivals, and Hodak is hopeful he can continue his form, starting with Saturday's game against this season's surprise package Pahang.
"It was a very important win against Terengganu," he told FOX Sports. "Especially for Keita, who scored his first goals for the team.
"I certainly hope that he will continue in this vein. Normally strikers gain plenty of confidence when they score, more so than any other player on the field.
"Now that he's no longer under any pressure I hope that he can continue. He's looking better in training and even in the game before Terengganu [a 2-0 loss to Selangor] he was okay."
Although Kelantan's lethargic start to the season has come as a surprise to many, who expected them to be serious contenders for the title, their lack of firepower up front is perhaps understandable given they lost three of last season's star attackers in Ghaddar, Malaysia international Norshahrul Idlan Talaha and flying winger Nurul Azwan Roya.
Hodak has brought in more-than-capable replacements in former T-Team duo Faiz Subri and Zairo Anuar Zalani, but admits their lack of depth is slightly worrying.
"The new signings are slowly finding their feet and with time, I think we can have a very strong first XI," the Croat added.
"The problems arise when they are unfit or out injured; we then struggle to replace them. We have very young, talented players in reserve but they need time."
Kelantan have an excellent chance to continue their surge up the table on Saturday when they visit the Darulmakmur Stadium to take on Tok Gajah, who led the rankings for the first five weeks until suffering back-to-back defeats to LIONSXII and Perak.
Given how competitive the season has been so far, Hodak is aware how important a win this weekend could be for the Red Warriors' hopes of reviving their title bid.
"We need to cut the gap at the top of the table and we are quite near now," the 41-year-old admitted.
"The difference between the top teams and the bottom teams are now very small. If you win, you're near the top but if you lose, you will drop to the bottom.
"But I don't think we need to be pressured. We will take it match by match and try to win as many games. If we do so, I think we can be up there [challenging for the title]."
Hodak was handed the reins at Kelantan midway through last season and led them to the treble by winning the Super League, Malaysia Cup and FA Cup, becoming only the second team after Kedah to achieve the monumental feat.
