Ratchaburi FC (THA) 1 v 1 Gamba Osaka (JPN)
Venue: Ratchaburi Stadium (Ratchaburi)
Kick-off: Wednesday, 19:15 (UTC+7)

While Gamba Osaka would have been disappointed to have settled for a 1-1 draw with Ratchaburi FC in the first leg, the Japanese side will feel they have the quality to navigate into the semi-finals despite having to play away.

Last week's stalemate was the first time Gamba did not win against Ratchaburi, having defeated the Thai side in their previous two encounters.

Gamba dominated the first leg but will need to be sharper as only one of their seven shots on target found the back of the net and that too in the 84th minute to help them salvage a draw.

Ratchaburi were fortunate to not walk away from the first leg with a deficit but the Thai side know they have to be more adventurous at home, managing only two shots on target last week.

Tampines Rovers FC (SGP) 1 v 2 Bangkok United (THA)
Venue: Jalan Besar Stadium (Singapore)
Kick-off: Thursday, 20:15 (UTC+8)

Tampines Rovers FC will be determined to make full use of their second chance when they host Bangkok United.

The Singapore side looked to be down and out after Thailand's Bangkok surged to a 2-0 lead in the first leg but Trent Buhagiar's 80th minute strike saw the deficit halved and Tampines will hope to maximise home ground advantage and advance to the semi-finals.

Bangkok, however, can be expected to be firing on all cylinders and will look for an early goal to douse Tampines' hopes of making a comeback.

It will be the fourth meeting between the sides, with Bangkok winning two of the previous encounters and Tampines one.
