Arsenal, Chelsea, Liverpool, Manchester City, Manchester United and Tottenham Hotspur all confirmed their intent to leave the newly-formed breakaway competition just 48 hours after confirming their intent to join.
And now Ceferin has welcomed their move to correct a “big mistake” and is now focused on “moving forward together”.
“I said yesterday that it is admirable to admit a mistake and these clubs made a big mistake,” read a statement from the Uefa chief.
“But they are back in the fold now and I know they have a lot to offer not just to our competitions but to the whole of the European game.
“The important thing now is that we move on, rebuild the unity that the game enjoyed before this and move forward together.”
Meanwhile, former Arsenal boss Arsene Wenger has told beinSport that the collapse of the ESL does not surprise him: “I’m not surprised it didn’t last long.
“I never believed from the start it would happen.
“It ignored the basic principles of sporting merit. If you ignore that you kill the domestic leagues, fans would never accept that. Rightly so.”
