Claude Puel called for the introduction of video technology after his Southampton side were beaten 3-2 by Manchester United in the EFL Cup final.
Southampton were beaten by an 87th-minute Zlatan Ibrahimovic header at Wembley, having recovered from two goals down.
Manolo Gabbiadini struck twice to cancel out goals from Ibrahimovic and Jesse Lingard, but the Italian had an earlier strike unfairly ruled out for offside.
Saints legend Matt Le Tissier described the call as “disgusting” – as documented in 16 Conclusions – and manager Puel led claims for video technology to be introduced.
“I would like of course the video for the future, for this situation for example,” the Frenchman said.
“For the moment in football without video, and just sometimes (there is) a bad decision and (it’s) against us for the team….
“It’s important to accept this but I am disappointed for the players and for the fans.
“It’s very hard when we see this game to lose this game but it’s football.
“Before the third goal we had the best situation, the best opportunities (to win).
“It is a big disappointment with the quality of this game. (And a) Frustration of course for all my players.”
