Selangor got off to a dream start, opening the scoring in the third minute after Alvin Fortes evaded two markers on the right before cutting back for Chrigor Moraes to sweep home from close range.

Persib tested the gloves of Sikh Izhan Nazrel in the 13th minute, Uilliam Barros’ powerfully struck shot from distance was, however, straight at the Selangor custodian.

The home side increased their advantage four minutes later when Moraes got through in the box but saw his shot hit goalkeeper Teja Paku Alam, with the unfortunate Patricio Matricardi knocking the ball into his own net in the subsequent melee.

Sikh Izhan then kept Selangor’s two-goal advantage intact with an incredible double save in the 37th minute, diving to his right to push away Luciano Guaycochea’s grass-cutter from outside the box before producing a brave stop to deny Andrew Jung on the follow-up.

Bojan Hodak’s message at half-time sparked life into Persib, with Jung forcing a one-handed save from Sikh Izhan in the 47th minute before steering home Berguinho’s pass a minute later.

The open game saw both teams having chances with Fortes firing wide after latching onto a half-cleared ball while Thom Haye’s curling free-kick was punched away by Sikh Izhan in the 77th minute.

Persib continued pounding at Selangor’s door with a Barros header going wide following a long throw-in from Robi Darwis before Julio Cesar’s acrobatic effort was well saved by Sikh Izhan.

The away side’s persistence eventually paid off in the 81st minute after Marc Klok sent substitute Adam Alis through, with Sikh Izhan getting a hand to the midfielder’s shot but not enough to keep the ball.

There was to be further agony for Sikh Izhan in stoppage time as his clearance hit Alis and landed inside the net as Persib sealed a remarkable win.
