Galatasaray are yet to win in the Champions League this season but welcome back one of their talismen against Benfica.
Burak Yilmaz's return to fitness has provided a boost for Galatasaray as the Turkish side attempt to deal Benfica their first Champions League loss of the season on Wednesday.
Portuguese champions Benfica have taken two wins from two in Group C and produced a shock 2-1 victory over Atletico Madrid in their last encounter in the competition.
Rui Vitoria's men now attempt to continue that run at the Turk Telekom Arena but face a tough task to keep Turkey striker Yilmaz at bay.
