"I’m delighted with the win, I thought Jefferson was amazing today," Brash said.
"He has so much quality and I finally feel our partnership coming through and I feel there is no Grand Prix this horse can’t win.
"We just missed out in Madrid and I was thinking it was going to be another unlucky year again, but it's great to be part of the exciting Super Grand Prix."
"It was an amazing crowd, especially when the Swedish guys ride they really get behind them and it’s great to feel that bit of atmosphere again at the shows, it brings the best out in the competitors."
