Paris Saint-Germain goalkeeper Kevin Trapp had a nightmare moment at the Bernabeu on Tuesday night as his mistake proved costly against Real Madrid.
The Ligue 1 champions were top of Group A on goal difference ahead of their Spanish rivals prior to kick off with both sides level on seven points.
However, Trapp’s error could ensure that Rafa Benitez’s side now have the advantage in the race to secure top spot and the French side may well be left hoping that either Malmo or Shakhtar Donetsk can do them a favour in the remaining two group games.
Nacho was the benefactor of the mistake, as he slotted home to break the deadlock in the Spanish capital in a relatively entertaining first half compared to the last time these two met a fortnight ago with the game ending in a goalless draw.
Meanwhile, the signing of Trapp in the summer left former first-choice stopper Salvatore Sirigu disappointed having lost his place in the side, although it remains to be seen whether or not he gets a recall.
Nevertheless, it is difficult to ignore the fact that PSG have conceded just six goals in 12 league games so far this season, which is unsurprisingly the best record in Ligue 1.
The reigning champions currently boast a 10-point lead over nearest rivals Lyon, but after disappointment in the Champions League in recent years, Blanc knows that his side must translate that impressive form onto the European stage.
