Jose Mourinho's arrival at Chelsea this summer has created a buoyant mood around Stamford Bridge with fans and players alike.
His first tenure was laden with success and it is hoped that he will be able to repeat this in his second spell.
He will need to replicate some of the brilliant signings he made in his first spell in order to bring trophies to the Bridge, which he is more than capable of.
Here is a list of the top five signings Mourinho made at Chelsea (in no particular order).
1. Petr Cech
Arguably one of the best goalkeepers in the world today, the reliable Cech has provided a solid foundation for Chelsea over the past nine years and holds the record for the longest time without conceding a goal in the Premier League (903).
The imposing Cech has been Chelsea's undisputed number one since Mourinho brought him to Chelsea from Rennes - dislodging Carlo Cudicini - due to his composure, imposing frame and agility.
He also saved three penalties during the Champions League Final of 2012, including Arjen Robben's effort in extra-time.
2. Ricardo Carvalho
The tough-tackling Portuguese centre-back previously played under Mourinho at Porto and followed him to Chelsea for a fee of around £20million.
He more than lived up to the hefty sum during his six-year stint with the club, forming a formidable partnership with John Terry at the heart of Chelsea's defence as they won consecutive Premier League titles.
He made over 200 appearances for the club before leaving to again join Mourinho, this time at Real Madrid.
3. Ashley Cole
England left-back Cole has been a club stalwart since he signed from Arsenal in a move shrouded with controversy.
He has been the club's most consistent performer for several seasons, providing an attacking threat whilst remaining difficult to beat defensively.
He played a vital part in Chelsea's Premier League title-winning squads of 2006 and 2010, and has been awarded the club's player of the season award twice.
4. Arjen Robben
Although his time at the club was comparably brief, Robben had a huge impact upon his arrival from PSV Eindhoven for £12million.
His pace and flair caused havoc for defenders throughout the Premier League, adding 19 goals to his numerous assists during his two-year stay in west London.
He became widely-regarded as one of the world's best wingers and has since gone on to win trophies at Real Madrid and Bayern Munich.
Chelsea also made a reasonable profit upon selling Robben to Madrid, recouping double of what they paid for him.
5. Didier Drogba
The word 'legend' does not seem to do the Ivorian justice.
Nine goals in nine cup final appearances - including the all-important equaliser and deciding penalty in the Champions League Final against Bayern Munich - sums up the man who always delivered on the big occasion.
After Chelsea splashed £24million on the powerful frontman - great things were expected and he delivered, finishing his time with 157 goals to his name.
Personally I feel that Drogba was one of the greatest all-round strikers ever to have played football as he possessed pace, strength and skill.
He will forever be remembered by Chelsea fans.
Honourable mentions: Michael Ballack, Michael Essien, Paulo Ferreira.
