Galatasaray and Schalke resume their respective Champions League campaigns on Wednesday as the two square off in Istanbul.
The Turkish side finished runners-up behind Manchester United in Group H, edging Cluj due to their superior head-to-head record. The Germans' performance in Group B was a bit more convincing, and they beat Arsenal to the top spot.
Much has changed for Schalke since December, however. Coach Huub Stevens was sacked on the 16th, and the Gelsenkirchen side have suffered a dearth of form. Indeed, Die Knappen have won just one out of their last 12 games in all competitions.
Amid this horrid run, star playmaker Lewis Holtby was sold to Tottenham, and Michel Bastos and Raffael have been brought in to bolster the squad.
Gala have experienced their share of changes as well, but theirs have been decidedly better. The Istanbul club remain first in the Turkish league and signed stars in the form of Didier Drogba and Wesley Sneijder in the January transfer window.
They looked strong in the group stage and will be well-prepared for the knockout rounds, having added two players who have previously won the Champions League.
