Dijksteel for Fisher and slot McNair into the back 3. I'd also probably bring Watmore on for Spence.
I've been banging on about it for a few games, but Dijksteel looks a bit off the pace.
Spence hasn't done too much wrong, but I think the way the game will go (Coventry sitting deeper in the 2nd half), getting someone with more trickery will help unlock that defence.
Plus with those changes we can push McNair back into defence, barring the set piece he's been largely anonymous in midfield.
