The Sea Robbers are currently leading the log table on goal difference and can go three points clear of Mamelodi Sundowns if they beat Black Leopards tonight.
"It's still a long way, it's still a long way," Mhlongo tells snl24.com/kickoff.
"They just have to convert their chances, so far they are not converting their chances, it's a little bit of a worry. But they are keeping the fight, it's a good race, that's what we need in this country, a league that is tight."
Mhlongo says it is not fair for people to lay the blame for failing to score goals solely on the strikers.
"No we can't say that, [it's] the strike force, since the likes of [Justin] Shonga arrived they've been fighting for the league, even last season, so we can't say that. It just happens sometimes that luck cannot be on your side. I think other players must come to the party.
"If you can check the other teams they don't have only two goalscorers, they've got many, look at Wits, Sundowns... anyone can score from defence to attack. So I think other players must come to the party not just the striking force, then we can say something.
"But for now they must convert their chances. This season is tight, don't disregard the likes of Cape Town City. Four points is nothing. In five games four points is nothing, this will go down to the wire.
"It will be a classic like when Pirates won the treble, Ajax [Cape Town] took it to the last minute before they won the treble. So I think it's gonna go that route, as you can see Sundowns are away but when they come back maybe Pirates will be leading by five points. But it's gonna go down to the wire, this season is tough."
