Bayern Munich feel "cheated" after some tight decisions allowed Atletico Madrid to advance from their Champions League semifinal, chief executive Karl-Heinz Rummenigge said.
Playing at home on Tuesday, Bayern won the second leg on Tuesday 2-1 but Atletico advanced thanks to Antoine Griezmann's away goal.
It was a classic counter-attack as Fernando Torres sent Griezmann racing through and the France international, played onside by David Alaba, kept his cool to whip the ball past Manuel Neuer.
Rummenigge said he believed Griezmann was offside when Torres released him through on goal, and also took issue with a penalty given to Atletico that Torres ended up missing.
"We feel a little bit cheated," the CEO said after the game. "The Atletico goal was offside, the foul for the penalty [which Atletico missed] was outside of the box.
"The referee had two matches in the last seven days. I don't know whether those UEFA guys can have too many matches, too. The UEFA delegate told me: 'It's a shame what he did.'"
Bayern midfielder Arturo Vidal insisted his side were still the better team, but the Chilean was left to rue missed opportunities to overturn the scoreline in the second half.
"I don't know why the ball did not want to go in ... with so many chances created in both legs," Vidal said. "I think we were superior in both games. We controlled possession, but didn't seize it.
"They take their opportunities well, and that's why they move into the final. From here to the final they will dream with us. They faced the best team in the world.
Bayern now turn their attention to securing the Bundesliga, where they enjoy a five-point lead over Dortmund with two rounds remaining. They will also face Dortmund in the DFB Pokal final on May 21.
"We are left sad, but we still have two titles that we hope to win. We are still the best team in the world, but sometimes the best doesn't always win," Vidal said.
"Football is sometimes like this. Today the best didn't advance, they were eliminated."
