Blues legend Lampard endured a nightmare start as manager as his side were hammered 4-0 at Old Trafford.
Chelsea started the game impressively and played the brighter football in the first-half, with youngsters Tammy Abraham and Mason Mount showing their potential and the former Aston Villa loanee hitting the post early on.
But the London side were ruthlessly punished by a number of key mistakes, with Marcus Rashford turning the game on its head with an 18th minute penalty after a clumsy foul from Kurt Zouma, while their three other goals came on the counter-attack.
Jose Mourinho was among those to criticise Lampard following the opening day drubbing, but Melchiot says any criticism directed at the rookie boss is premature.
