Five-time former World Cup winners lost to Belgium 2-1 in Kazan on Saturday (AEST) and were eliminated from the tournament, while the Red Devils progressed to the World Cup semi-finals.

"Belgium were more precise but we had more goal-scoring opportunities. We haven't been very efficient today but I can't say that we've played poorly, it was just bad luck. It wasn't our day," Becker told journalists on Friday night.

The goalkeeper added that the team was not blaming midfielder Fernandinho for the own goal that gave Belgium the lead early in the first half.

"Situations like this happen in football. We're supporting him [Fernandinho] as a friend and as a [team-] mate," Becker said.

The 2018 FIFA World Cup kicked off on June 14 and will continue until July 15, with the final set to be held at Moscow's Luzhniki Stadium.
