River’s draw with Rosario Central on Sunday might have handed the initiative back to Boca Juniors in the title race but Marcelo Gallardo’s side ensured that it will go to the wire after a 3-0 win over Atlético Tucumán on Wednesday evening.

River needed to ride their luck at times and certainly El Decano will point to a razor-thin offside decision that denied them a first half equaliser and a good spell after half time but ultimately Los Millonarios quality told.

Jorge Moreira had thumped the visitors ahead inside a minute but Atlético remained right in it until Sebastián Driussi’s shot was helped into his own net by Ignacio Canuto on the hour mark.

Pity Martínez slotted in the third and River cruised to victory meaning just a point separates the two Buenos Aires giants at the top with four matches to play.
