Neither side really has an out and out goalscorer at the top end of the pitch this season.
Edwards will be assured that his side can pitch in with goals from all over the pitch.
Despite spending more than most countries' space budget, Chelsea continue to look to fill that void.
This season, the one table that Mauricio Pochettino's side do sit top of is 'big chances missed'.
The Argentine's mis-firing side have missed a staggering 40 big chances in games this season.
In a game like today's, not taking these could lead to an upset against The Hatters.
Rob Edwards spoke about what he looks for from Barkley in their side:
"Ross is a player that still needs an element of freedom to get the best out of him - as long as we can get a couple of non-negotiables from him - he’s got to be able to feel the game to be at his best.
“He’s an artist, really. You’ve got to allow him a little bit to go and do his stuff. We love having him here, he’s come into the group and shown loads of humility, worked incredibly hard.
“There’s still more to come from him, which I think is really exciting as well. We’ve given him a home, we’re helping each other. He’s helping us and we’re helping him enjoy his football again. When players have a home, they feel more valued, you’re going to get the best out of them.”
Ross Barkley will be more motivated than ever to show his old employer the talent that spurred them to buy him from Everton.
The midfielder has kick-started his career since joining Luton in the Premier League.
Home fans will be hoping he can pull the strings for a famous victory today at Kenilworth Road.
