  1. Kidderminster 1-0 West Ham

    Five minutes left.

  2. CLOSE!

    Chelsea 1-1 Plymouth

    Kidderminster have deserved this, they have been brilliant. The have been the better team

  4. Chelsea 1-1 Plymouth

    This has been an incredible performance from League One Plymouth.

    They're up against £250m worth of attacking talent at the moment.

  5. Chelsea 1-1 Plymouth

    Great ball swung into the six yard box from Hakim Ziyech towards the head of Romelu Lukaku, but the Belgium international's feet are stuck in cement and he cannot get off the ground.

    Dan Scarr heads clear.

    Six to go.

    Steve Wilson

    West Ham are 10 minutes from ignominy.

    Dion Dublin
    Former Aston Villa striker

    That is totally embarrassing from Yarmolenko. What are you doing? I'd be embarrassed with that.

  8. Kidderminster 1-0 West Ham

    West Ham keeper Alphonse Areola is required to dive and tip away a corner that loops right under his bar. Kiddy at the right end of the pitch.

  9. Kidderminster 1-0 West Ham

    Desperation.

    Andriy Yarmolenko throws himself to the floor after zero contact in the box. It's embarrassing.

  10. SUBSTITUTION

    Attacking change from stand-in Chelsea boss Arno Michels.

    Midfielder Mateo Kovacic off, forward Timo Werner on.

    Billy Wild: This is what happens when you have no depth to the squad. It’s why West Ham fans are frustrated at the lack of investment. But fair play to Kiddy, they deserve to win this.

  12. Kidderminster 1-0 West Ham

    Into the final 10 minutes. It's so close now for Kidderminster.

  13. GREAT SAVE!

    Chelsea 1-1 Plymouth

    Michael Cooper is having a storming game, another reflex save to deny Kai Havertz from close range.

    10 to go before we see extra-time and possibly penalties.

  14. Kidderminster 1-0 West Ham

    Dion Dublin
    Former Aston Villa striker on BBC Match of the Day

    West Ham have been so poor all over the pitch.

  15. Kidderminster 1-0 West Ham

    The stands are bouncing at Aggborough now. They know just how special this is.

  16. Chelsea 1-1 Plymouth

    Chelsea earn back-to-back corners, the count is up to 15.

    Again the win the initial header, again Plymouth clear the follow-up.

  19. 'Bang out of ideas'

    Kidderminster 1-0 West Ham

    Rob Green
    Former West Ham goalkeeper on BBC Radio 5 Live

    You have to say West Ham are bang out of ideas. The number of players who are stood on the ball with their hands up saying 'where are you? Give me an option'.

  20. SUBSTITUTION

    Kidderminster 1-0 West Ham

    Nikola Vlasic off, Pablo Fornals on. West Ham throwing everything they have at this.

    Harriers also make a switch with Sam Austin replaced by the more defensive-minded midfielder Devonte Redmond.
