If we start with Gestede and Miller again at Ipswich, there's no way Mason will be in there in place of Vuckic.
The Championship pace does seem to have caught Vuckic out. Chucked in at the deep end, he was poor against Leicester but showed some composure on Tuesday. He's adjusting at gthe moment, and the more he plays the better he'll get.
I can't see Malky going anything but 4-5-1 against Ipswich up there, though after his Tuesday game, Rudy will be unlucky not to have another crack from the off.
