There was a problem with Nico's car getting out of the garage. We knew the last thing we wanted was to have our two cars on the same piece of track, because if there had been an incident both cars would get caught up.
"So the plan was to split them, but when we came to release Nico's car we had a problem releasing it, and it left the garage 20 or 30 seconds later than we planned. So then we had both cars together.
"Plus, Nico was getting squeezed between Michael behind him and Rubens [Barrichello] in front of him, and we didn't manage it very well as a team.
"Michael was annoyed after the second or third lap got spoiled, but when I explained what happened he was okay - just frustrated. But I think all of us were frustrated today because we did have a reasonable car around here and, as you saw in Q2, we were looking forward to final qualifying and we cocked up."
Rosberg apologised to Schumacher after qualifying for holding him up, and said he too was a bit annoyed by what happened.
