Arne Slot must learn from Liverpool mistakes at Galatasaray after Steven Gerrard demandLiverpool face Galatasaray in the first leg of their last-16 tie on Tuesday and Arne Slot must get his starting XI right, having lost 1-0 to the Turkish side earlier in the seasonView 2 Images Arne Slot has selection decisions to make (Image: James Gill/Getty Images)Arne Slot needs no reminding of how difficult Tuesday's match against Galatasaray can be for Liverpool. The 1-0 win in September came courtesy of a Victor Osimhen penalty, due to a stray arm by Dominik Szoboszlai. At the time, Liverpool sat top of the Premier League table, having made a strong start to their title defence, with five wins from six. But that trip to Istanbul wasn't a blip, more of a sign of what was to come. It remains to be seen whether Slot is brave enough to take Gerrard's advice and use Ngumoha ahead of Gakpo on the other flank.
