Istanbul: The UEFA Champions League round of 16 begins with a heavyweight meeting on Tuesday as Galatasaray host Liverpool in a high-pressure first leg at Ali Sami Yen Spor Kompleksi (RAMS Park) in Istanbul. Kickoff is scheduled for 8:45 p.m. local time. According to Azerbaijan State News Agency, the winner across two legs will advance to face either Paris Saint-Germain or Chelsea in the quarterfinals. For Galatasaray, the setting could hardly be more fitting. RAMS Park, a 52,000-seat fortress often labeled 'Hell' by visiting clubs, has long been one of European football's most intimidating venues. Liverpool now return to that cauldron seeking redemption after suffering defeat in the same stadium earlier this season.
