The Chilean has been speaking about how different England's top flight is to what he was used to in Spain with the Catalan side.
Alexis Sanchez has hailed the Premier League, following a successful first season in England with Arsenal.
The Chilean made a big-money switch to the Emirates last summer, sensing his playing opportunities at Barcelona may be limited with the forward line of Lionel Messi, Neymar and Luis Suarez.
Sanchez says he enjoys the competitive, unpredictable nature of England's top flight, and thrives in the pressure that comes with each and every fixture.
He told the Arsenal website: "Here in the Premier League you can get beaten 3-0 by a team near the bottom of the table. That’s not an unusual thing in English football and is also why any prediction ahead of matches can be very deceptive.
"Regardless of how good or bad the team you play against is, you can feel that there’s a huge crowd and pressure everywhere you go. I really like that.
"Every team is really strong. For instance, you cannot take for granted any in-game score in this league. Any team can score goals in the last minutes of the game and I like that."
Sanchez says the Premier League differs to La Liga, in the respect that he knew some games at the Nou Camp were going to be easier than others.
The 26-year-old says that isn't the case in England.
He added: "When I played for Barcelona, I knew that some home games were going to be easier than some others as the team had plenty of confidence. That confident mentality helped Barcelona players to win games.
"However, a confident mentality may not be enough when it comes to the Premier League. Your opponent is going to run and fight endlessly, regardless of your confidence levels."
