Chelsea manager Jose Mourinho has admitted he can still scarcely believe that Arsenal passed up on the chance to sign former captain Cesc Fabregas this summer, but boy is he glad they did.
Fabregas quite surprisingly swapped Barcelona for Stamford Bridge in a £27 million deal that was wrapped up before the World Cup started in June, but only after Gunners boss Arsene Wenger decided he couldn't make room for his former captain at the Emirates.
The 27-year-old has wasted no time in once again proving his Premier League credentials and Mourinho is clearly impressed, telling the Daily Mail that he's the final piece of a puzzle that he fully expects to deliver success this season and beyond.
Wenger's snub under the microscope
Mourinho couldn't help but take a shot at Wenger in his glowing praise of Fabregas though, like many Arsenal fans still amazed the Gunners couldn't make an allowance for a midfielder who was nothing short of sensational during eight seasons in North London.
He said: 'For me it was a surprise that he (Fabregas) came. We knew the type of player that we wanted but I never thought there was a chance Fabregas would come.
'I always thought he would stay in Barcelona, or if he returned to England it would be with Arsenal.
'When we knew it was possible it completed the jigsaw, leaving us with a team that still has many years to grow with its own identity.'
Cesc moves on to play pivotal role for Chelsea
There's no question that Fabregas is flourishing at Chelsea and the statistics certainly show he's already developed an understanding with strike star Diego Costa.
Fabregas has directly assisted four of Costa's seven goals so far this season, while also scoring for the first time in Chelsea Blue himself against Schalke in the Champions League on Wednesday night.
This Sunday promises to the first genuine test of Mourinho's new expensively assembled jigsaw though, with Fabregas and Nemanja Matic up against Yaya Toure and defending champions Manchester City.
If the Spanish schemer continues to shine in his second Premier League spell though there will be plenty of uncomfortable questions for Wenger to answer about his former linchpin, particularly with Arsenal due to face Chelsea at Stamford Bridge on October 5th.
