Southampton overcame all odds to beat Liverpool in the semifinals of the EFL cup and progress to the finals.
Puel’s men were ahead by 1-0 after winning on home soil and went to the Anfield and got business done with a Shane Long strike sealing a 2-0 win on aggregate.
Southampton will face either Manchester United or Hull City in the final and Puel is looking to win the encounter.
“It is fantastic for all the squad and a good reward for their hard work,” Puel told BBC Sport.
“It was difficult to find this opportunity to play a final at Wembley. In the two legs we deserved the win. We were fantastic in the first leg at home and we had chances in the first half [at Anfield].
“In the second half it was difficult but now we go to Wembley, not just to participate but to win this cup.
“I have been there once, just to watch France beat England.”
Southampton captain Steven Davis, meanwhile, was over the moon with his side’s run to the final and now wants to make history.
“It is huge, we have progressed every year since I have been here but I have been waiting for a chance to get to a final,” he added.
“In the first leg we should have been further ahead. We have the opportunity to go and create some history.”
