Anwar is a fan of the Reds and met our head coach and chief executive officer during a rare break from political duties, with the ASEAN summit currently taking place in the city.
The chat took place for around 20 minutes, with footballing matters discussed, including the Maybank Challenge Cup clash being staged at 13:45 BST on Wednesday.
Anwar received a United jacket, which he quickly put on to show his support for the club.
ASEAN All-Stars head coach Kim Sang-sik and skipper Sergio Aguero, who shares his name with Manchester City's legendary striker, also presented a signed shirt to the Malaysian leader.
