The Seagulls drew 0-0 on Tuesday night at Chelsea, who joined Manchester City, Manchester United, Liverpool, Arsenal and Tottenham in pulling out, and Barber said those responsible for the proposals should be held to account.
Barber said, “It’s been a very difficult 72 hours and the FA and Premier League now need to review what’s happened, who was responsible, the damage it’s done to the game over the last 72 hours and take the appropriate action.
“I think there’s real disappointment and many of the people involved, people we count as colleagues, we have worked with for many years.
“I think this hasn’t just happened over 72 hours, it’s been weeks and months in planning and that feels very disappointing.
“There’s a lot of bridges that now need to be rebuilt and it needs to be the six clubs back to the 14.”
Barber said the Super League had caused “a huge amount of damage” and that the game’s governing bodies must ensure it can never happen in future.
“The Premier League and the FA now need to make sure that their rules are tightened significantly to make sure this never happens again,” Barber said.
“There’s no doubt there’s a huge amount of damage been done in the last 72 hours and it’s going to take some time to repair. We need to make sure this doesn’t happen again and we learn from it.”
When asked if the six English clubs should now face a points deduction, Barber said: “I’m not the judge or jury on this one. It’s not for me to determine, that’s up to the Premier League.”
