On Wednesday, Galatasaray face Schalke at the Türk Telekom Arena. This game brings together one side in very good form, sitting comfortably at the top of the Super Lig, and another team that haven't won in four games and are 27 points off first place in the Bundesliga.
While Galatasaray have been much better than Schalke domestically, the Germans have much more recent experience in Europe than their Turkish opponents.
The Royal Blues had an amazing run in the 2010-11 Champions League campaign in which they reached the semifinal. The next year, Schalke played 14 times in the Europa League before being knocked out in the quarterfinals. On the other hand, Galatasaray haven't moved past the Round of 16 of either European cup since 2001.
Here's a list of five players to watch on Wednesday.
