I've said before that I don't think BR trusts Iheanacho. Much like with Praet.
Iheanacho should be the main striker at the moment but it looks like he's back on the bench at best with Vardy playing irrespective of form and Daka competing with Iheanacho as back up.
From Iheanacho's perspective, he's done everything asked of him and is, if anything, further away from a regular start.
I'd definitely not sell as Vardy will spend some of the season injured. However I expect BR would happily trade Iheanacho and Praet for a RW and another creative player.
If we could get Madueke and Coutinho (loan), he probably thinks that he doesn't need Iheanacho. Or even replace Iheanacho with Edouard.
