Galatasaray midfielder Nordin Amrabat has admitted the ambitious Turkish team faces an uphill task to stay in the Champions League after its 1-1 draw at home to Schalke 04 in its last-16, first-leg.

The Royal Blues take a slim advantage back to Gelsenkirchen for the return leg on March 12 after Burak Yilmaz gave Galatasaray an early lead, before US midfielder Jermaine Jones leveled for Schalke on the stroke of halftime.

"The formula for victory is very simple: We need to score and win, but it won't be easy," said Amrabat after Wednesday's game.
