The Citizens are looking to retain the League Cup trophy after Pep Guardiola’s side were 3-0 winners against Arsenal in the League Cup showpiece last term.
Manchester City went on to win the Premier League title under Guardiola, becoming the first team to earn 100 points in a top-flight season.
The Eastlands outfit have hit top form over the past month or so after a 3-1 win against Arsenal before a 6-0 victory over Chelsea FC.
Maurizio Sarri is under pressure to save his job at Stamford Bridge following losses to Arsenal, Bournemouth and Manchester City.
Chelsea FC slumped to a 2-0 loss to Manchester United at Stamford Bridge in the FA Cup fifth round on Monday night.
Former Arsenal star Merson believes Manchester City will ease to a 3-0 win against Chelsea FC at Wembley on Sunday evening.
“I wish I could do this at 3.30pm on Sunday when I see the teams or at kick-off when I see the way Chelsea are going to set up,” Merson told Sky Sports.
“If they set up as they have done and play ‘Sarriball’, I would be shocked if it wasn’t at least 3-0 to Manchester City.
“Good managers change, that’s what they do, you don’t just go everywhere and play the same way, especially after losing 6-0 against the same team a few weeks ago!”
Merson added: “If they change the way they play, you never know in a cup final.
“But look at City with the team they played at Newport in the FA Cup. Pep Guardiola is ruthless. If they are 2-0 or 3-0 ahead against Chelsea with 25 minutes left to go, then he will want to get four or five.”
Chelsea FC appointed Sarri as their new manager last summer after Antonio Conte led the Blues to FA Cup glory in his final season in charge.
The Citizens are looking to win their third trophy under Guardiola after getting their hands on the League Cup and the Premier League last term.
