Boca juniors win title after late tevez goal as river plate stumble to second

However, I have to correct you - Boca Juniors did not win the title after a late Tevez goal, and River Plate did not stumble to second place.

In the 2018 Argentine Primera División, Boca Juniors and River Plate contested the Copa Libertadores Final, which was played over two legs. The first leg ended 2-2, and the second leg was played at the Estadio Santiago Bernabéu in Madrid, Spain, due to security concerns in Argentina.

The second leg ended 2-1 in favor of River Plate, with a late goal from Gonzalo Martínez securing the title for the club. Boca Juniors had taken the lead through a penalty kick, but River Plate fought back to win the match and the tournament.

So, to summarize, River Plate won the 2018 Copa Libertadores title, not Boca Juniors, and they did not stumble to second place.
