Andre Villas-Boas arrived at Stamford Bridge in the summer of 2011 amid much fanfare following a season in charge at Porto where he led them to four trophies, including the Europa League, without losing a single match.
Having previously worked at Chelsea as an opposition scout under Jose Mourinho, the inevitable comparisons with the former Blues boss were soon made, particularly given the fact they had both arrived from Porto on the back of vast success.
Villas-Boas 's first match in charge was a 0-0 draw away at Stoke City, but four straight wins followed, and the emergence of young players such as Juan Mata and Daniel Sturridge in a new-look front-three signified a new, expansive style of play which the manager was eager to implement.
Problems first began to emerge when Arsenal were the visitors to west London at the end of October, and Villas-Boas's favoured high defensive line was ruthlessly exposed, culminating in a 5-3 home defeat.
A week later, we made the short trip across London to take on Queens Park Rangers in what proved to be a highly controversial fixture. Both Jose Bosingwa and Didier Drogba were sent off for the Blues as we lost 1-0 to a penalty, Villas-Boas not happy with the consistency shown by referee Chris Foy.
A home league defeat against Liverpool soon followed, and when Kenny Dalglish's side returned to inflict another on the Blues a fortnight later, this time eliminating us from the Carling Cup, Villas-Boas's position, as well as the much publicised high defensive line, came under scrutiny.
With the vultures circling and the pressure on his young shoulders mounting, he appeared to have turned the corner in the month of December with impressive victories against Newcastle, Valencia and Manchester City.
Oriol Romeu, the midfielder who Villas-Boas had unearthed from Barcelona, had begun to make an impact with some tough tackling and intelligent distribution in the middle of the park, and the capture of the Spaniard appeared to highlight the new manager's ability to spot emerging young talent.
Performances, though, once again began to dip over the Christmas period, and after three successive draws we were soundly beaten 3-1 at home to Aston Villa.
A 2-1 win away at Wolves in early January temporarily lifted the gloom, but a record of two league wins from our next seven matches saw us drop to fifth in the table, with qualification for next season's Champions League in jeopardy.
A 3-1 first leg defeat to Napoli in the Champions League, coupled with a 1-1 home draw in the FA Cup fifth round against Birmingham left our hopes of securing any silverware hanging by a thread, and after we were beaten 1-0 away at West Bromwich Albion in the league, the board made a decision to part company with the 34-year-old.
