During the planned second leg on 24 November 2018, scheduled for El Monumental, the home pitch of River Plate, numerous River Plate fans threw glass bottles and stones at the Boca Juniors team bus headed to the stadium, injuring numerous players as a result. CONMEBOL postponed the match and moved the second leg to Europe for 9 December 2018 in Madrid, a neutral site, for security and travel reasons. Both sets of fans attended the match as River Plate won 3–1 after extra time (5–3 on aggregate) to lift the trophy outside of South America for the first time.
