Ederson enjoyed the victory over Crystal Palace and insisted Lazio “have to win” the Italian Super Cup against Juventus.
The Aquile earned a 1-0 friendly win at Selhurst Park  on Saturday thanks to Miroslav Klose.
It was their last pre-season test ahead of the Stadio Olimpico showdown with Juve on August 18.
“It was a good game and it’s always fun to play in England,” Ederson told Lazio Style Radio.
“The fans are extraordinary. Despite the fact they were losing, the Palace supporters never stopped singing. It’s a pleasure to play in this atmosphere and we are satisfied with the performance.
“We are preparing well for the challenge with Juventus. It is a game we have to win.”
The Super Cup is between Scudetto holders Juve and Coppa Italia winners Lazio.
