Netherlands struggled for the full 90 minutes in Tuesday's Euro 2012 qualifier at home against Hungary, but Oranje eventually recorded a hard-fought 5-3 win to maintain their perfect score in Group E.
Goal.com spoke with full-back Erik Pieters about the match and the PSV defender was far from pleased with his individual performance.
"I was at fault for Hungary's second goal of the game. Gera was my direct opponent and I allowed him too much space. He dropped deep for a while and I kind of expected him to make a run forward. Things went different though. I should have marked him closer," said Pieters to Goal.com.
The young defender went on to say that Tuesday's match was completely different to Friday's game, when Oranje beat the Hungarians 4-0 in an impressive display.
"The biggest difference was that we didn't win enough second balls. That made it difficult to keep the pressure on and we couldn't really play our own game.
"We aren't qualified for Euro 2012 just yet, but we really shouldn't let this slip away any more. Winning our remaining home games should be enough."
Ajax defender Gregory van der Wiel pointed out that Oranje didn't underestimate their opponents, but didn't know where it went wrong for the Dutch.
"We were simply not focused enough at the start of the second half. They scored an early goal and we really struggled. We didn't underestimate them, but I don't know what the problem was. Bert van Marwijk told us to be alert after the interval, but apparently nobody listened," he said to Goal.com.
The right-back then reflected on the individual battle between him and Balazs Dzsudzsak and expressed his satisfaction with the way he kept winger quiet, despite his involvement in two goals.
He added: "We gave away the goals way too easily. I haven't really seen much of Dzsudzsak though."
