Mauricio Pochettino has asked Chelsea fans not to judge him on “winning titles” as the Blues target their first domestic trophy for six years.
Chelsea’s last domestic silverware was the 2018 FA Cup, although they have since won four international honours.
Pochettino, who took charge at Stamford Bridge last summer, can win his first prize in England after previous spells at Southampton and Tottenham.
“For me, that is not the way to judge a coaching staff,” said the Argentine.
“It’s about being competitive and winning, but there are too many factors that influence.
“I think [victory on Sunday] is not going to increase my popularity or the way the fans are going to see us.”
Pochettino used the example of Jurgen Klopp to reinforce his point, saying the Liverpool manager’s reputation was not affected by a near four-year wait for his first trophy at Anfield.
“Klopp was good before he arrived at Liverpool,” he said. “Now he’s won the Champions League and the Premier League.
“The thing is to be in the right moment in the right club that trusts in you, with the tools and the responsibility to win.”
Liverpool, meanwhile, head into Sunday’s final aiming to win the first of a potential four trophies this season.
The Reds lead the Premier League by four points and are into the Europa League last 16 and FA Cup fifth round.
The game is a rematch of both the Carabao and FA Cup finals of 2022, both of which Liverpool won on penalties.
“This is my first final with Liverpool so it’s going to be something very special for me and the team,” said Argentina international Alexis Mac Allister.
“[Winning] the World Cup helped me to realise that I really want to win more trophies and so Sunday is a big opportunity. It’s what I wanted when I signed for the club.”
Chelsea drew 1-1 at home to Liverpool on the opening day of the season but lost 4-1 at Anfield at the end of last month, when Nunez struck the post from a penalty after Benoit Badiashile was adjudged to have fouled Diogo Jota.
That defeat was followed by a 4-2 home loss to Wolves.
