Hansen wrote in the Telegraph: "It is a compelling argument, and no doubt the Stamford Bridge faithful will have a view on the greatest to ever wear the Chelsea shirt, but for the full package I can't believe there has been anyone better.
"When you look at the best there has ever been, you list all their attributes. More often that not, even outstanding players have one or two flaws.
"There is no weakness in Lampard. He scores goals - his return is extraordinary for a midfielder - he can defend, he has character and temperament, he finds the net with either foot, can head the ball and, perhaps most importantly of all, he is a winner - the ultimate professional on and off the park.
"Allied to all this, you look at his longevity, the medals he's won, his appearance record since he joined Chelsea, how few games he missed through injury, particularly at his peak. I don't recall him ever missing a match with a slight niggle here and there. For any manager he's played for he must have been considered the dream professional."
