Former Chelsea midfielder Emmanuel Petit believes they can build on their Champions League triumph.
Petit reckons they can challenge for the Premier League title next term.
He told The Sun: "Can you imagine if this team can improve offensively, individually and collectively?
"They will be even more difficult to defeat because they've found the right balance defensively, it's very hard to score against them… I think they've got a bright future.
"The manager has signed for two more years, that proves what he's done is brilliant after six months and I think they'll be even more competitive next season."
