I think that's what explains the Mertens rumor. Lampard wants a versatile striker.  Matter of fact, we have so many versatile players. Mertens can play LF and as a second striker. Ziyech can play CAM and RW. Mount can play LW and CAM. Ruben as a CAM or CM. There's even Gallagher on loan who can virtually play any single position in midfield.
