Shearer felt Arsenal targeted Christie during their 5-1 win.
"Arsenal identified this weakness, which was down Fulham's right-hand, particularly Christie. And time and time again, whether it was Iwobi, whether it was Welbeck, they got into those areas and dominated in that position.
"Christie was constantly going forward, not worrying about defending. Three v three, look at Christie here - he's walking.
"His team is in trouble here. His first thought has to be, get back and help. Now look at him on the halfway line there, he jogs, Monreal is away and all of a sudden he realises and it's too late.
"Ball into the box, first goal, punished because you're not thinking defensively. It was so alarming.
