Branislav Ivanovic headed in an extra-time winner to send Chelsea into the Capital One Cup final.

The Blues booked their place at Wembley with a 1-0 triumph over Liverpool after a heated 120 minutes of football at Stamford Bridge.

Diego Costa was fortunate to escape a red card for appearing to stamp on Emre Can and Martin Skrtel.

Costa was in the thick of everything at the Bridge in this sensational semi-final and he was denied a penalty when he was hacked down by Skrtel in the box.

But it was Blues who had the last laugh as Ivanovic headed in Willian's free-kick at the start of the additional 30 minutes needed to separate the two teams.

Chelsea will play either Tottenham or Sheffield United in the final at Wembley Stadium.
