The Italian deployed Hazard in the position during the 1-1 draw in the first leg.
But as Chelsea must score to advance to the quarter-finals, Lampard has used the example of Fernando Torres, who scored two goals at the Nou Camp in the 2012 semi-finals, to illustrate how useful an out and out striker can be against the Catalan giants.
"I would certainly consider picking Morata to lead the line with Eden Hazard and Willian behind.
"The striker has to play better than he has done in recent weeks. He needs to be physically stronger and hold the ball up more. He has the physical attributes and technical ability to do this.
"But what Morata can also provide is a target for Chelsea players to aim at and someone who can run in behind.
"He can do that job more naturally than Hazard, who without the responsibility of playing up front can get more involved in the game himself.
