The LIONSXII are currently second in the league after a storming start to the campaign and are just two points behind leaders Kelantan, but had their Malaysia FA Cup bid ended on Tuesday when they lost to Terengganu 1-0 on aggregate.
Having now gone three games against V. Sundramoorthy's charges without a loss this season, Mat Zan does not believe they have what it takes pose a real title threat.
"To win the league you need to have consistency, experience and the X-factor," Mat Zan said, according to Channel NewsAsia. "To be frank, the LIONSXII are quite ordinary.
"They are predictable, especially in attack."
The LIONSXII's main threat up front this season has been captain Shahril Ishak, who has grabbed seven goals in the league but even he is not considered a genuine out-and-out striker, something Mat Zan believes the Singapore outfit badly need.
"We were rarely troubled. We know what to expect from the LIONSXII and we can deal with it," Mat Zan added.
"If only they had someone prolific up front, like the Fandis [Ahmad] and the Sundramoorthys, then things would be different for them."
Terengganu are on course to meet Kelantan in the final of the FA Cup, provided both teams get past their semi-finals against Sime Darby FC and Kedah respectively.
And Mat Zan has warned the Red Warriors his side will not only be looking to battle them for cup glory, but in the league as well, in a bid to secure their first-ever title.
"We were beaten to the title by Kelantan last season and the desire to win it for the first time is driving my team forward," Mat Zan declared.
"Kelantan are still the team to beat in the MSL [Malaysia Super League] but we are fighting them every inch of the way."
Terengganu resume their league campaign on Saturday when they entertain Johor FC, while LIONSXII take on T-Team at the Jalan Besar Stadium.
