Sepp Blatter says the ruling in favour of football clubs unwilling to release their players for Olympic duty has paved the way for rich clubs to get more "easy money".
The Fifa president said today that he was saddened and surprised by the Court of Arbitration for Sport's (CAS) ruling yesterday because he thought Fifa and IOC could "trust these people".
The CAS ruling handed power to clubs who wish to stop their players competing in the tournament, but Blatter insists he will use Fifa's ruling Congress to have it enshrined in the rules that clubs must release under-23s for the Olympics.
"For 2012 we will have the solution. We will establish it in our regulations or even in our statutes," he said. "The Fifa Congress is sovereign and we will bring this to the next Congress.
"I gulped when I heard the decision. It's really sad to see such a decision was handed down, putting in danger the entire football tournament.
"Now some clubs are saying they want to be paid for players who take part. The rich clubs - they want more easy money, even for the Olympics."
Blatter added the decision was the biggest blow of his tenure thus far. "It's the most disappointing thing that has happened to me in football since I became Fifa president.
"We were reluctant to go with CAS when it was first set up, but it was the will of the IOC, so we thought we could trust these people."
IOC president Jacques Rogge told a news conference he would work with Blatter to resolve the situation - and that it could be easily done if the tournament was included as part of the official international calendar.
"The football tournament is very important and we are very keen on having the best tournament we can," he said.
"The solution is very easy - if Fifa would put the Olympic men's tournament on the combined programme then it's solved because then clubs would be under obligation to release their players."
