It will feel like an age for both sides, as the result has been beyond doubt for more than an hour now.

Tatsuhiro Sakamoto is withdrawn by Coventry

Kaine Kesler-Hayden is on for the final few minutes.

In fact we'll have an added four minutes.

Four minutes left to play.

Can Swansea at least head home with a goal to their name?

Southampton flood forward in what has been a rare second-half attack from the visitors.

This was probably always the plan to get him on for the last 10 minutes.

Josh Maja and Callum Styles head on for West Brom.

Karlan Grant and Charlie Taylor are taken out of the firing line.

With this game now just rumbling towards its inevitable conclusion, the television cameras have turn to focus on Southampton's interim boss Tonda Eckert.

It's a great strike from Mason-Clark but an equally great save from Josh Griffiths.

They've got to try and get some hold-up play in the Coventry half.

Isaac Olaofe, Karoy Anderson and Luke Berry come on for Greg Docherty, Sonny Carey and Conor Coventry.

It gets no easier for West Brom.

Ellis Simms is off but 10-goal Brandon Thomas-Asante is on to face his former side for the final 17 minutes.

Charlton have improved somewhat in the second half, not that it would have taken much after the first-half showing.

Still, chances have been few and far between.

Tyreece Campbell has just carved out the best of them, cutting in from the left before flashing a shot just over the bar from the edge of the area.

Haydon Roberts and Yu Hirakawa join the fray in time to see Swansea's Kaelan Casey send his shot from the centre of the box high.

Scott Twine and Neto Borges were the ones to come off.
