Newcastle United reached their first cup final since 1999 by beating Southampton in the Carabao Cup semi-final.
Longstaff scored again 16 minutes later following the withdrawal of Miguel Almiron.
Southampton’s Che Adams scored from 25 yards but the hosts still won despite Bruno Guimaraes being sent off.
Guimaraes received a direct red card eight minutes from time for a gruesome challenge that caught Samuel Edozie on the ankle.
Referee Paul Tierney initially showed the Brazilian midfielder a yellow card but, following an intervention by the video assistant referee, changed the decision to a red card after watching the incident on a monitor at the edge of the pitch.
Manchester United leads 3-0 against Nottingham Forest in the second semi-final, with the second leg of that encounter taking place at Old Trafford on Wednesday.
The final takes place at Wembley on Sunday February 26 and will be Newcastle’s first final appearance since losing 2-0 to Manchester United in the FA Cup in 1999.
More soon.
