Former-Chelsea star Ruud Gillit has been impressed with Roberto Di Matteo's side this season, and believes there's more to come from the Blues' exciting attacking playmakers.
The Stamford Bridge icon hailed the achievements of last year's Champions League and FA Cup-winning team, but the ex-Netherlands international is looking forward to watching the new attacking Chelsea side develop.
Roberto Di Matteo signed Eden Hazard, Oscar and Victor Moses over the summer, overhauling Chelsea's attacking options, and the front trio, including Spain star Juan Mata, has started the season in fine form.
Speaking to the Chelsea official club website, Gullit said: "I've been very impressed. Robbie wanted to change a few things because when you take over halfway through a season it's not easy.
"He started with the fundamentals, the defence, and he won a lot with that. He's now starting to build something offensively, but we haven't seen the best of Chelsea yet, that still has to come, but I'm very pleased with the way the team has progressed."
He's bringing the good football back, he knows how to do that," explained Gullit.
Hazard, Oscar and Mata have operated as a front three, playing behind Fernando Torres in the early part of this season, and Roberto Di Matteo's side have had a lot of success.
The Blues currently sit top of the Premier League table, four points clear of nearest rivals Manchester United.
And Gullit, a former-World Player of the Year, paid tribute to last year's trophy success, as Chelsea have carried their good form forward from last season through to this campaign.
"I just felt it was destiny, I said it throughout all of the games, and also on television, and that's how it turned out," Gullit said of Chelsea's run to the Champions League final.
"For me, it was just a great feeling that Chelsea won the competition because they had wanted it for so long and then finally got it at a moment when you least expected it, and that's the best feeling," Gullit continued.
Chelsea face a trip to White Hart Lane in their next Premier League encounter, and a reunion with former-boss Andre Villas-Boas. Spurs have picked up after a slow start to the season, and recent history suggests Chelsea are in for a tough match at the weekend.
The Blues haven't won at Tottenham since 2005, but the Stamford Bridge side are in good form, and will be looking to extend their lead at the top of the table.
