Faced with heavy competition from fellow forwards Ashrin Shariff, Norikazu Murakami as well as attacking midfielders Therdsak Chaiman and John Wilkinson, Masrezwan could only manage 20 appearances (majority as substitutes) in the entire season.
However, Masrezwan injured his anterior cruciate ligament in training and thus finished the season as the club's third highest scorer with only ten goals.
However, his international career has been marred by injuries and poor performances, most notably in the 2001 Southeast Asian Games where his miss against Thailand contributed to knock Singapore out of the competition in the group stages.
As of 2008, despite being named in the 26-man provisional squad for a friendly against Australia and the World Cup Qualifier match against Lebanon, he did not make the final list.
Masrezwan was named as one of the 20-man national squad which will travel to Vietnam for the Ho Chin Minh City International Football Tournament in October 2009, his first call-up in nearly three years.
