The Blues have the tough task of breaking down a Clarets side who’ve not conceded in seven games - and shipped just nine league goals all season.
How does John Mousinho go about doing so. This is how we think his side will line up at Fratton.

2. GK Nicolas Schmid
Will wonder how he came out on the losing team given how quiet the Austrian was on Tuesday night against Millwall. | National World

4. CB Marlon Pack
Went pressing for Millwall's goal on Tuesday without having the desired impact on an otherwise strong showing. Interesting how things develop moving forward with Shaughnessy and Atkinson now in contention. | National World
