Banfield will be wondering how they are not taking a lead to Quito next week after having the better of their Copa Libertadores playoff first leg against Independiente del Valle but only coming away with a 1-1 draw.
An injury time penalty scored by Maximiliano Barreiro pulled the visitors level and would probably make them favourites to now progress to the final round of qualifying.
Julio César Falcioni was back in the dugout for the first time since undergoing throat surgery over the summer and the iconic coach was almost given a perfect welcome back gift with just minutes on the clock when Jesús Dátolo volleyed the ball against the post after a poor clearance by goalkeeper Hamilton Piedra.
Dátolo would again rattle the crossbar with fierce, long range effort during the first half and the referee also waved away a couple of penalty appeals as Banfield struggled to find a breakthrough.
That would eventually come in the 70th minute when referee Diego Haro would award a penalty for handball and Darío Cvitanich made no mistake in slotting into the top corner.
Banfield were a minute away from taking an advantage to Ecuador but in stoppage time, Haro spotted a push by Gonzalo Bettini in the six-yard box and Barreiro cooly pulled Independiente del Valle level.
The two sides will meet next week in Quito for a place in the third qualifying round against either Nacional or Chapecoense.
