Neymar put the visitors in command in the first half before a double from Luis Suarez pushed Luis Enrique’s side towards the final four. Van der Wiel replied with a deflected shot but despite the late rally, PSG face a seemingly impossible task at Camp Nou when they meet again on Tuesday.
“We had to be better defensively, we let them score too easily,” he told Canal+. “They have scored three goals away from home. We are very disappointed – it’s a really bad result.”
PSG went into the match handicapped by the absence of several regulars from their starting XI, including the suspended duo of Zlatan Ibrahimovic and Marco Verratti, but the right-back refused to use that as an excuse.
“Did we have too many players missing? No, I don’t think so,” he added.
The French champions also lost their lead at the summit of Ligue 1 on Wednesday evening as Lyon leapfrogged them with a 2-0 home win over Bastia.
If PSG are to progress in Europe, they will need to score at least three times at Camp Nou on April 21.
