Newcastle - What Could Have Been
Tottenham have been drawn to face UEFA Cup holders Sevilla. Spurs booked their place in the last eight with a 6-4 aggregate win over Portuguese side Braga, winning both legs of the tie 3-2.
Osasuna, who eliminated Rangers this week, face Bayer Leverkusen. The third Spanish side in the draw, Espanyol, will take on Portuguese giants Benfica.
The ties will be played on April 5 and 12.
