No time for slip-ups
Chelsea (eventually) made their way past the potential banana skin that was Preston North End in the third round of the FA Cup at the weekend, and they will be eager to ensure there are no slip-ups in this competition too.
Mind you, when it comes to the League Cup, the Blues are rarely on the end of a giant-killing.
Since being eliminated by Burnley on penalties in the fourth round in 2008-09, the Londoners have won each of their last 15 League Cup matches against sides from a lower division, scoring a whopping 53 goals in the process.
How the sides shape up
Michael Carrick makes four changes to the side that lost late to Aston Villa in the FA Cup at the weekend.
Matt Clarke, Morgan Rogers, Sam Greenwood and Josh Coburn drop out with Dael Fry, Jonny Howson, Matt Crooks and Emmanuel Latte Lath coming in.
It’s three changes for Chelsea, who bench Armando Broja, Mykhailo Mudryk and Alfie Gilchrist.
In their place, Malo Gusto, Noni Madueke and Conor Gallagher start for the visitors.
Chelsea fixtures leave Boro feeling Blue
To say Chelsea have had the better of recent fixtures between the club would be an understatement.
In fact, the Blues have won their last nine meetings with Boro in all competitions by an aggregate score of 21-0.
In English football history, only Liverpool have won more consecutive games against an opponent while keeping a clean sheet each time – 10 games versus West Bromwich Albion between 1997 and 2010.
