Real Sociedad manager David Moyes wondered how his side came away with all three points against a mighty Barcelona side. Real Sociedad beat the Catalans 1-0.
Moyes said: "The win feels similar to the early days at Everton.
"How was I ever going to get a result against the likes of Arsenal, Liverpool, Man United at that time?"
"We've talked about Barcelona in my previous clubs, at Everton and at Manchester United. I've watched them with admiration and we used to wonder how to possibly get a result against them," said Moyes.
"Tonight I had the opportunity; it was a long night, we scored early and I would like to have given them a harder game. We did make it very difficult for them, though.
The Scot said he is relishing the opportunity to compete against the top clubs like Real, Barca and Atleti.
"I would like to be competing against Barca, Real Madrid, Atletico, Valencia and Sevilla at the top of the league. To do that we have to make the squad stronger."
He also added that he expected Barca would play a depleted side against them due to the busy fixture list.
"I expected Neymar and Messi to maybe be on the bench," said Moyes.
"I've managed a very big club, you have a big squad and a lot of games. The big games come later for these teams - April time - and you have to give the big players rest to keep them fresh for
"I thought Luis Enrique made the right decision and the players that played tonight are really good players. He knows his squad the best and in his position I would probably have done the same thing.
He also advocated to include a winter break in England, where the clubs play almost three games in a span of five days.
"The winter break should definitely be considered in the Premier League. We're able to give the players a week off, then we came in and trained for a week before tonight. It would be great for the teams in England and great for the managers as well, to feel they could have a break after that hectic Christmas period."
