UEFA chief Aleksander Ceferin praised Manchester City for breaking first from the Super League group last night.
City's withdrawal was quickly followed the Premier League five other members - with the whole project now 'suspended' this morning.
Ceferin said: "I am delighted to welcome City back to the European football family.
“They have shown great intelligence in listening to the many voices - most notably their fans - that have spelled out the vital benefits that the current system has for the whole of European football; from the world beating Champions League final right down to a young player's first coaching session at a grassroots club.
“As I said at the UEFA Congress, it takes courage to admit a mistake but I have never doubted that they had the ability and common sense to make that decision.
“City are a real asset for the game and I am delighted to be working with them for a better future for the European game."
