Chelsea finished 10th in the league last season but are on course to win the Premier League title this season after Chelsea boss Antonio Conte revolutionized the team after taking over last summer.
Chelsea legend Frank Lampard has praised Conte for the massive job he has done at Chelsea this season.
“It’s an incredible turnaround,” Lampard told Sky Sports.
“To come in from where they were last year – they had a very difficult season.
“We all know the game against Arsenal when they got beaten pretty well, and then he moved to three at the back.
“The boss will be really pleased with the way they’re playing, how they know their jobs. Every player on that pitch has a system.
“And people are now emulating that system throughout the Premier League, playing three at the back.
“But I think Chelsea are the one team that do it brilliantly in every position.
“And I think they’ve got people in those positions that are so important to that system.
“[Cesar] Azpilicueta has the legs to play on that right side, David Luiz has settled in straight away centrally.
“Victor Moses and [Marcos] Alonso play as full-backs when they’re defending and wingers when they’ve got the ball.
“And then they’ve got that bit of magic with [Eden] Hazard, [Diego] Costa, Willian and Pedro, so it’s a complete team.
“But you have to give the manager huge credit to get them where they’ve got so far.”
