Colwill played the entirety of Chelsea's stunning 3-0 victory over Paris Saint-Germain in the final of the revamped tournament, which took place across the United States.

And asked whether Chelsea could build on that success to win either the Premier League or UEFA Champions League, Colwill replied: "Yeah, definitely.

"I said at the start of this tournament that our plan is to win it and people looked at me as if I was crazy.

"So I'm going to say the exact same thing now going into the Premier League and Champions League.

"This is the biggest trophy I've ever won. I think the Club World Cup will be bigger than the Champions League and we were the first team to win it.

"It was a statement victory and, in the future, if we keep winning trophies, then everyone will give us the love that we deserve.

"But we'll only know that in the future. I think we're ready, and we'll see next season."

Chelsea finished fourth in the Premier League 2024-2025, with a 1-0 victory over Nottingham Forest on the final day, in which Colwill scored the winner, sealing UEFA Champions League football for the upcoming 2025-2026 season.

The average age of Chelsea's starting line-up in the top flight last season was 24 years and 36 days – the youngest for a team in a single campaign in the competition.

But it mattered little as the Blues enjoyed a first full season under the tenure of Enzo Maresca, with the Italian also leading it to glory in the UEFA Conference League.

Its success at the FIFA Club World Cup also marked the a big triumph for co-owners Todd Boehly and Clearlake Capital, who took charge of the club in 2022.

Chelsea's transfer policy under the American businessman has seen it focus on bringing in young players on long-term contracts, while also paying out big fees.

This summer alone, the Blues have already made seven signings, including the arrivals of Jamie Gittens, Joao Pedro, Liam Delap and Estevao.

Joao Pedro has made an instant impact, becoming the first Chelsea player in the Premier League era to score three goals across his first two starts for the club in all competitions.

While questions have been asked about the Blues' transfer policy, Colwill believes Chelsea now has a squad capable of emulating its past.

"We're a team and that's in the Chelsea identity. You stick together no matter what. I think players like John Terry, Frank Lampard, Didier Drogba, they started that and we're carrying it on," he said.

"They were all amazing players, the best players who won a lot but we've got the best players in our team – young players for sure – and that's our plan: to win the biggest trophies for Chelsea.

"We're definitely capable of doing it. I think we've shown that. Everyone said that PSG were the best team in the world, but we won 3-0."
