Man Utd squad confirmed for Chelsea clash with Cavani set for debut
The west Londoners will lock horns with the Red Devils at Old Trafford on Saturday evening in a match that could see either side strike a blow into the other's hopes of finishing in the top four.
Lampard's troops will enter the match having won only two of their five league games this season, in which they've conceded a worrying nine goals.
The Blues have already come up short against defending Premier League champions Liverpool and will be looking to put on a better showing against their top-four rivals.
Merson hasn't been impressed by what he's seen of Lampard's troops this campaign and reckons the former Chelsea midfielder could find himself under intense scrutiny from the board if his side leaves Old Trafford empty-handed.
