The Saints recorded back-to-back 1-0 wins, with Nathan Redmond netting in the St Mary’s tie two weeks ago before Shane Long struck in injury time at Anfield on Wednesday to secure a 2-0 aggregate win.
Report: Saints knock Liverpool out to reach EFL Cup final
Now with the club’s first trip to Wembley since winning the Football League Trophy in 2010, Puel has set his sights on lifting the trophy – against one of Hull City or Manchester United, who battle it out for a final place on Thursday.
Speaking to Sky Sports after the game, Puel said: “Fantastic for all the squad and it is a good reward because of all their very hard work.
“To find this opportunity to play in a cup final is fantastic, over two legs we deserved it, because we were fantastic in the first leg at home with just one goal with many opportunities.
“Now the goal is to go to Wembley and not just to participate and I hope to win this cup, it’s fantastic for all the supporters, the squad, the staff.
“The second half was difficult for us because there was many chance for Liverpool, but in the first half we had two or three chances and could have made more of a difference.
“It is a great reward for the squad and over the two legs I think we deserved to qualify.”
Southampton lost to Manchester United in their only other appearance in a League Cup final, in 1979, but reached this stage of the competition without conceding a goal.
