Former Blues hero believes Croatian playmaker could be \"like Xavi or Iniesta\" to the Stamford Bridge club and admits he was surprised Spurs stood firm over £40m offer in the summer.Chelsea legend Ruud Gullit reckons the Blues still need Tottenham midfielder Luka Modric and has tipped them to make another move in the January transfer window.Modric was Chelsea\'s main target in the summer but they failed to land the Croatian despite a number of bids which culminated in a £40 million offer in the final days of the transfer window.The 26-year-old is now in talks over a new contract at Tottenham but Gullit believes Chelsea are still lacking creativity and will make a fresh move for Modric in January.“The player Chelsea still need, for me, is Modric,” Gullit said at the Golden Foot awards in Monte Carlo.“They have great players all around the pitch but he has something Chelsea doesn\'t have at the moment. He is creative and dominates the passing game in the midfield – he could be like Xavi or Iniesta are to Barcelona.“I was surprised Tottenham didn\'t accept £40m because they are known to sell their best players for good offers. I think Chelsea will try to sign Modric again in January and maybe this time they will get him.”Chelsea have made a strong start to the season under new manager Andre Villas-Boas and sit third in the Premier League after seven games, three points behind leaders Manchester United and Manchester City.Gullit, a former player and manager at Stamford Bridge, has been impressed with the attacking style of the team but believes Villas-Boas should not be judged until he has been in charge for two full seasons.\"I really like the style of football I am seeing from Chelsea under Andre Villas-Boas,” added Gullit. “I know the supporters there want to see quick, attacking football with creativity.“They will be contenders for the Premier League and the Champions League this season, for sure.“The new coach probably needs two full seasons before we can start to judge him. The team may have some problems this season but there is no point in appointing a young coach if you\'re not going to be faithful to him and back his ideas.”
