This is what I would like to see and how I think Leicester will shape up, which is pretty much guaranteed to be the same system every week at this stage.
Herrera's energy will be important. A three man midfield will hopefully allow us to overrun Kanté and Drinkwater, although Albrighton often tucks in to help out. Lingard making runs inside will give us a 4 on 3 advantage at times. It's important that we capitalise when on top. Fellaini's aerial threat and lack of pace will render him pretty much useless against a side containing Huth, Morgan and Kanté. No need for the big guy, in my opinion. I bet LvG will start him ahead of Herrera though. Set-pieces.
Damian is a better defender than Rojo and can position himself better to work with Blind to shut Mahrez out by tucking inside next to Blind, to show him onto the outside. We don't need to see much attacking from him, as we have Rooney and Martial combining on our left in my formation.
I would prefer to see Morgan over Carrick for this one. He is more mobile and better equipped to handle a mobile Okazaki.
Martial vs Simpson could be our best bet at scoring. He's the Leicester weak link. Martial will have a lot of time on the ball should we get it out to him. The Leicester full-backs tuck inside and only close down at the last second. So if he roams into pockets of space or stays far wide, he should have enough time on the ball either way to play his natural game.
Rashford will probably be bullied physically by the two giant veteran centre backs. But his ability to run into the channels and dribble will unsettle them at times, so his main role will be to occupy defenders rather than being a main attacking threat.
Kanté vs Rooney will be intriguing. If Wayne's touch and passing aren't up to scratch, the little man will be onto him like a flash and look to start counter attacks. We need Rooney to perform and feed Martial the ball regularly.
Vardy is Vardy. A few weeks ago he said that Smalling was the toughest defenders he'd faced this season. Yet he still managed to wriggle away to score last time out. We need stop him from springing in behind.
Hopefully Rashford can occasionally pull a defender out of place to allow runners like Lingard and Herrera to break into the space from deeper starting positions.
