I guess we won't see any Turkish teams in the Champions League this season. First, Fenerbahce got eliminated by Lille, and today Galatasaray failed to win against the Swiss champions, Young Boys.
As much as Lille is a strong team from the top of the French league, one of the strongest in Europe, you would expect more from Galatasaray against YB. Galatasaray dominated the league last season, scoring an impressive 102 points, but tonight, they were unable to do anything and the game must've been a disappointment for the Turkish fans.
Something bad happened to Turkish football over the recent years, it could be that due to tough economic situation in the country (high inflation and all that) clubs got poorer and can't attract or retain talented players.
