The European soccer body UEFA is taking legal action against FIFA over Infantino's failed plan to sell World Cup profits to private investors.

Infantino wanted to get $4.2 billion from investors, but his plan was stopped after many people got upset.

UEFA led the opposition and its members agreed to boycott FIFA events while the plan was active.

UEFA's lawyers told FIFA they might take legal action and want to keep all related documents and messages.

The letter from UEFA's lawyers was sent on Friday and seen by the media on Monday.

The letter named 18 FIFA executives who should keep their documents and messages as evidence.

UEFA warned FIFA not to destroy any evidence related to the plan.

The Swedish soccer federation said UEFA is looking for an alternative candidate for FIFA president.

UEFA wants to end Infantino's presidency, saying he has lost the trust of world soccer.

Infantino withdrew his plan after UEFA and others opposed it.

Here's what you need to know about FIFA's private investment plan and the backlash.

FIFA's plan to let a private company run the World Cup was met with anger from UEFA.

The plan would have given control of FIFA's commercial operations to a private company until 2038.

UEFA's lawyers said legal action is likely and that the plan was not good for soccer.

Infantino has support from some regions, but many are against his plan.

A senior FIFA adviser quit over the World Cup investment proposal, calling it a bad deal.

Infantino's path to keeping his job is unclear after the backlash against his plan.

There were reports that Infantino might get support from the US administration, but this was denied.

The private equity plan has caused big problems for Infantino since it was revealed.

Infantino seemed likely to be re-elected, but now his future is uncertain.

The plan could have given Infantino a new role with a higher salary after his presidency.

The first federation to withdraw its support was Wales.

The deadline for candidates to run against Infantino is November 18.
