Top of the table Lions will be looking to maintain their stay by claiming another league double over the Seladangs
LionsXII meanwhile had ensured that they were the ones keeping the pace with a hard-fought 1-0 win over neighbours Johor.
On Tuesday night they will be playing hosts to Norizan Bakar's Perak at Jalan Besar Stadium.
A 2-1 win earlier in the season at Perak Stadium against a side that looked to be challenging for the title and was labelled the best team in the league by V.Sundramoorthy, had strengthened the credentials of the fledgling team.
For Perak, the defeat set off a run of four matches without a win, including three consecutive defeats, that only ended last weekend with a 2-1 win against a weak Kuala Lumpur side.
The poor form of forward Lazar Popovic has also been of concern with the Serbian looking likely to get the boot by the end of the transfer window.
The striker woes of LionsXII meanwhile look to have ended despite a string of untimely injuries.
Khairul Nizam's second strike in as many games on Saturday was the winning goal at Pasir Gudang Stadium, and the forward has quickly eased into the target man cum poacher role.
An injury setback earlier in the season had robbed the former Courts Young Lions player of the opportunity to make an impact sooner but since returning and replacing the injured Sufian Anuar, Khairul has looked perfectly in sync with his team-mates.
V.Sundramoorthy will be hoping to keep up the good form of his players with another win and extend their lead at the top of the Malaysian Super League table, though defending champions Kelantan would by then have three matches in hand.
