Claudio Bieler did in fact sign to play for Quilmes AC in Argentina this afternoon, as was mentioned this morning. He's set to begin training with the club tomorrow. The club has even acknowledged at the end of an article on the club's website about today's training that Bieler was signing with the club. But unlike fellow signing Mariano Uglessich, there was no release and there were no photographs of Bieler's contract signing.
The reason for that apparently has to do with Bieler's contract with Sporting and MLS. There's been no mention by Sporting or the league about Bieler being out of his contract, which is probably part of the reason that there can't be an "official" release.
With this news though the announcement of the termination of Bieler's contract with Sporting KC can't be far behind. And it's a bit bitter sweet in a way. Bieler was quite successful in his first season, scoring 10 in league play, and adding another in the Open Cup. His biggest goal though came in the 2013 playoffs against the New England Revolution that saw Sporting KC advance in extra time on their way to MLS Cup. This season though Bieler saw his time reduced drastically, he played just 421 minutes in MLS play, starting only four games and scoring just two goals as he found himself behind Dom Dwyer and his remarkable form in 2014. Bieler added two more goals this season in the Champions League, but for Designated Player money, the contribution needs to be higher.
