Chelsea will be the favourites at Bramall Lane but that doesn't mean Sheffield players won't be able to put the Blues to the test, says former Arsenal defender Martin Keown.
In his column in the Daily Mail, the Gunners legend writes: "In one vs one situations, I’d back Chelsea’s wide men. But the Blades are outstanding at doubling up on their opponents. Basham and O’Connell fly forward and George Baldock and Enda Stevens provide excellent cover.
"Midfielders Sander Berge and Ben Osborn sprint forward but they can dash back just as quick.
"Wilder’s side enjoy being the underdogs. They’ve proven that this season and will embrace the challenge of playing Chelsea on Saturday."
