In December 2011, the FAS announced that Safuwan will join the newly formed LionsXII in the 2012 Malaysia Super League.
The LionsXII finished runners-up in their debut season.

Safuwan formed a strong understanding with Baihakki Khaizan in central defence as LionsXII won the 2013 Malaysia Super League with the competition's best defensive record.
He contributed with five goals in 26 matches.
Amid interest from Thai, Indonesian and rival Malaysia Super League sides including T-Team, he put pen to paper in a new two-year deal with LionsXII in November 2013.

Safuwan capped off his league performances by becoming the first male recipient of the annual Straits Times Athlete of the Year award in 2013.

Following the departure of regular defensive partner Baihakki in 2014, Safuwan formed a new partnership with new LionsXII recruit Afiq Yunos.
He also showed his versatility with lauded displays in advanced midfield and attacking roles.
Safuwan's performances up front and LionsXII's poor goal scoring form led to head coach Fandi Ahmad having to consider playing him as a forward in more games.
Safuwan started in an advanced midfield role behind striker Khairul Amri in a Malaysia Super League match away to Sarawak on 15 March.
On 25 March, he scored a late winner over Perak to send LionsXII up to 5th in the league table.
He scored his second goal in as many games four days later as LionsXII drew 1–1 with T-Team and followed it up with the opener off a Shahfiq Ghani cross against Sime Darby on 5 April.
