First-half goals from Robert Rojas and Rafael Santos Borre had River on track to sensationally overturn a 3-0 deficit in the semi-finals in Sao Paulo.

Champions in 2018, River had a goal ruled out early in the second half and a penalty call overturned after Rojas' red card, Palmeiras holding on for a 3-2 aggregate victory.

Rojas produced a brilliant header from a Nicolas De La Cruz corner before Borre nodded in a Matias Suarez cross in the 44th minute.

River thought they had levelled the tie in the 52nd minute, but Gonzalo Montiel's volley was ruled out for offside following a VAR check.

But River were awarded a penalty just two minutes later for a challenge by Alan Empereur on Suarez, only for the decision to be overturned following a VAR check.
