Selangor's appointment of its technical director Michael Feichtenbeiner as caretaker head coach towards the end of the 2020 Malaysia Super League competition not only helped them rebound from a series of underwhelming results, it also allowed several of their younger players to make their first team debuts under the German's guidance.
One such player was 20-year old midfielder Aliff Haiqal Lokman Hakim Lau, whose competitive Selangor first team debut came in their September 20 league match against UiTM FC, when he replaced K. Sarkunan at the start of the second half. He then went on to make two more league appearances and a Malaysia Cup outing, all as a second half replacement.
