Victory for Banfield would have secured the first place in the Copa Diego Maradona final but an injury time winner from Diego Valoyes gave Talleres three points and leaves Group B wide open ahead of the final round of fixtures.

It took only four minutes for Franco Fragapane to nod Talleres into the lead and yet the tournament’s breakout star Giuliano Galoppo struck his fifth goal of the campaign to bring Banfield level. The 21-year-old midfielder arriving in the box to hit an accurate first-time shot past young goalkeeper Joaquín Blázquez.

With half time moments away a heavily deflected Tomás Pochettino shot put Talleres back in front and when Luciano Lollo was sent off soon after the restart, Banfield’s luck had appeared to have run out.

However a penalty converted by Juan Álvarez two minutes from time looked to have given Banfield a vital point until deep in stoppage time when Valoyes volleyed a winner.

Banfield host San Lorenzo next weekend knowing that a win will still be enough to win the group.

San Lorenzo and manager Mariano Soso face some hard questions after another defeat left them out of contention. Gimnasia were the visitors to the Nuevo Gasómetro on Monday and with three points it was the Lobo who remain in the picture for a place in the final.

Both sides had hit the woodwork during the first half before Eric Ramírez finally headed Gimnasia in front quarter of an hour from full time.

The lead was fleeting with Ángel Romero squeezing a headed equaliser past Jorge Broun and yet there was still time for Gimnasia.  Ramírez could have won a penalty when tripped by Fernando Monetti and although it angered the visitors Lucas Barrios came off the bench to fire an 88th minute winner.

Gimnasia host Atlético Tucumán needing a win and for Banfield and Talleres to slip.

Unión kept their slim hopes alive in the Complementacíon phase with a win over Aldosivi yet require a huge swing in results if they are to climb above Rosario Central in Group A.

Mauro Luna Diale gave Unión a first half lead and although a Francisco Grahl penalty levelled things up in the 78th minute a wonderful Martín Cañete free-kick immediately put the visitors back in front.

Juan Manuel García wrapped it up in stoppage time and now Unión must hope to beat Patronato at home and Central lose away to Lanús with a large enough change in goal difference to leapfrog the leaders.
