The return of Jamie Vardy.
He's only played one 90 minutes in more than four months (vs. Belgium in the World Cup). So he should be pretty fresh.
He's had four weeks to train and rest since his red card against Wolves. The frustration of watching England from the subs bench all summer and then knowing he'd fecked up to get sent off will have been nicely winding him up.
I'd be very surprised if he isn't out of the blocks today like Usain Bolt. If I know anything about him, he'll be very up for today's game.
If we're otherwise solid and create him with some chances, he'll win it for us today.
