Mourinho's first season back in West London ended in disappointment, as the Blues went without winning a trophy. A third place finish in the Premier League and a semi-final exit in the Champions League suggested that the Blues weren't too far off winning silverware under 'The Special One' again.
Now, Mourinho has spent heavily this summer in order to try and get his side over the finishing line in multiple competitions. Left back Filipe Luis, midfielder Cesc Fabregas and striker Diego Costa have all arrived, whilst loan stars Thibaut Courtois and Kurt Zouma have returned to the club after temporary spells away. Familiar faces such as Ashley Cole, David Luiz, Frank Lampard and Samuel Eto'o have all left the club, and one departure in particular will be key to Chelsea's hopes this season.
Lampard, now 36, hit over 200 goals for the Blues during 13 superb seasons, establishing himself as one of the top goalscoring midfielders in Europe. Alongside Nemanja Matic, Chelsea had to find a ball playing midfielder with better technique than Ramires - and whilst they found on in Fabregas, it appears that the former Arsenal man may have been second choice.
Today, manager Mourinho admitted that he tried to bring Real Madrid star Modric to the Blues. In 2012, Mourinho snapped up the Croatian in a £33m deal, and was looking to reunite with the Croatian - only to shunned by the former Tottenham maestro.
"I called Modric only privately but he doesn't want [to join] Chelsea," Mourinho said. "You know I really appreciate Luka Modric and his qualities. But he stays in Real Madrid."
Never really considered a goalscorer, Modric loses out to Fabregas from that aspect, but the 28-year-old is a classy deep lying playmaker who would former an outstanding partnership with Matic - but it wasn't meant to be for the Blues, three years after a long-running saga surrounding their bid for Modric.
