None of the Argentine sides to begin their Copa Libertadores campaigns this week managed a win and on Thursday evening, Transición champions Lanús became the fourth as El Granate slumped to a 1-0 defeat at home to Nacional.
Undoubtedly impacted by the delayed start to the season, Lanús were off the pace and a little ragged but still created chances in what was an open game with Uruguayan league runners-up Nacional.
Sloppy defending allowed Hugo Silveira to tap the visitors in front midway through the first half and in truth it could have been worse for Lanús at half time with the erratic Esteban Andrada in goal spreading panic throughout.
El Granate pushed for an equaliser and did muster some decent efforts on goal but the absence of Miguel Almirón driving forward from the midfield was obvious.
Nacional held on for the valuable away win with relative ease and Lanús now have to prepare for a difficult trip to Chapecoense, who won their opener earlier in the week.
Lanús 0 – 1 Nacional
