Spurs, who sacked manager Jose Mourinho earlier this week, take on Manchester City at Wembley trying to land their first trophy since 2008.
Winning silverware would go some way to making up for what has been a poor season, with a Premier League title challenge wilting into a race to get into the top four and an embarrassing Europa League exit at the hands of Dinamo Zagreb.
But if Spurs can finally get over the line in a showpiece event, following a League Cup final defeat in 2015 and the Champions League final loss in 2019, Lloris says they will have repaired some of the damage.
“There is still a chance of a European place next season in the league. Before that, we need to win all the games,” the France captain said.
“Then, a trophy is always welcome, especially after many years without a trophy at the club. It will not change the feeling of the season because we had so many ups and downs, but we can save the season, yes, of course.
“We can save the season and obviously to finish in a good way will help the confidence of the players of the club next season.”
Spurs hope the appointment of Ryan Mason, a 29-year-old former midfielder, can help galvanise the club in pursuit of their ambitions before the end of the season.
Mason, who has only been coaching for two years, has been thrown in at the deep end and will come up against Pep Guardiola and one of the best teams in Europe.
But Mason believes his side should not be discounted, even if Harry Kane is ruled out with an injury.
“He’s a great manager, he’s one of the best in the world, there’s no doubting that,” he said. “He’s been at City for a while now, so he’s got that as well.
“They’ve got a lot of familiar faces within their set-up, they know how they play. But we’re Tottenham and I’m sure they’ll be thinking of us as well.
“This is about Tottenham, this is about the football club, this is about the group of players, our fans, everyone.
“This isn’t about me, my ego, me going up against Pep. This is Tottenham Hotspur against Manchester City.
“I’m sure we’ll be doing all we can to get the better of them and likewise they’ll be doing the same for us.
“But it’s a cup final, we’ve seen over the years, one-off games, anything can happen. We’ll go there believing, with confidence, that hopefully it will go our way Sunday.”
