Crystal Palace's manager Patrick Vieira felt his team were unlucky to lose 1-0 against Leeds on Tuesday night and admitted the Eagles' profligacy in front of goal was a major source of frustration.
An injury-time penalty from Raphinha secured all the three points for the home side at Elland Road, leaving the visitors to rue a series of missed chances.
Christian Benteke, a second half substitute, spurned a glorious opportunity just five minutes after coming as he headed a Wilfried Zaha's cross wide from close range. The Belgian had another opportunity late on, but Leeds keeper Illan Meslier stopped his shot just before it crossed the line.
