Even on loan, how much would Icardi cost - the fee and wages etc?
And as you alluded to, is Icardi an all-rounder or near one? Lampard would want a mobile striker (this doesn't apply to Giroud but he does the next bits well), a striker that can hold up the play, link up with others, bring others into play - and also obviously, a striker who can score goals. Batshuayi is obviously no Icardi but a poacher striker doesn't seem to suit Lampard's style of play.
