The former German international was asked if his new club could win a World Cup.
The journalist who bizarrely asked Bastian Schweinsteiger whether an American football club could win the World Cup has offered an apology.
Derek Henkle, a video journalist with AFP, put the question to Schweinsteiger, as to whether his new club Chicago Fire can win the World Cup - a tournament for national teams only.
Henkle has since clarified that he was actually inquiring if the MLS side could win the Club World Cup, a competition which they can qualify for by winning the Concacaf Champions League.
Henkle told The Telegraph in an email:
"I'm truly sorry if I offended anyone. As a general assignment video reporter, I was seeking facts at a press conference.
"I get that I named the wrong trophy and greatly appreciate Schweinsteiger attempting to clean up the question for me. It was a classy move.
"My question missed its mark, but it has allowed me to become better educated on the ins and outs of soccer.
"I may have been one of the only general assignment guys in the room - but I believe, like a lot of Chicago, that Bastian Schweinsteiger's arrival presents an amazing opportunity for those of us who want to experience soccer to more fully embrace the sport."
"I report on everything ranging from presidential politics to science - and I'm the first to admit that I don't know everything, but I do ask."
The former Manchester United player, signed a one-year deal with Chicago Fire, with the option of signing for an additional year.
