Lanús and Independiente should be commended for even staying with River Plate this season as Marcelo Gallardo’s men made it a record-equalling 28 matches unbeaten after coming from behind to defeat Atlético Rafaela. Diego Montiel had given La Crema a first half lead with a thunderous long range strike but a superb Leonardo Pisculichi free kick and an Ariel Rojas goal turned the match around and ensured that River reestablished their four-point lead at the top. Lanús had closed that gap momentarily after earlier defeating San Lorenzo in La Forteleza. Lautaro Acosta’s superbly worked goal after 20 minutes proved to be just enough to see off the Copa Libertadores champions, who now have a concern over captain, Leandro Romagnoli. After a heavy fall, the influential midfielder has fractured his elbow and will miss the remainder of the season with the hope that they will have him back for the World Club Championships in Morocco. Boca Juniors saw off a below-par Defensa y Justicia in La Bombonera thanks to a first half brace from Juan Manuel Martínez to remain in fifth and Estudiantes made hard work of defeating 10-man Quilmes in La Plata.
