They say you should never go back. But what if you're Jose Mourinho? The Special One has officially signed a four-year deal with Chelsea following his departure from Real Madrid.
Mourinho, who enjoyed a hugely-successful spell as Chelsea manager during his three-year reign from 2004 to 2007, will be looking to bring the one trophy that escaped him at Stamford Bridge: the UEFA Champions League.
Despite his failure to the land the prestigious trophy, he is widely regarded as the greatest manager in Chelsea's history. Coming back to Chelsea could prove to be a mistake - who knows if he can live up to his previous success at the Bridge, which saw him win 67% of his games?
One thing that is almost certain is a big-money transfer this summer. Mourinho will be looking to bolster a leaky defence and also sign a prolific goalscorer, if he opts to send Romelu Lukaku back on loan for more experience.
During his time at Chelsea. Mourinho spent a whopping £225m on talented players which saw the most successful period in Chelsea's history. Michael Essien, Ricardo Carvalho, Didier Drogba, Ashley Cole and Andriy Shevchenko were just a select number of huge names that helped to propel Chelsea amongst the elite clubs in European football.
Success will be expected almost instantly with Mourinho at the helm, starting with the UEFA Super Cup against Bayern Munich and his old rival, Pep Guardiola.
He will also be expected to fight for the Premier League title with Manchester United and Manchester City expected to push for the title. And of course, Mourinho will be expected to pose a serious threat on the European stage, as they look for a third consecutive European trophy.
Mourinho's return has attracted a lot of attention throughout the world of football and many are happy to see the Special One back in the Premier League.
It's fair to say that his last job at Real Madrid was not his most successful and he will be looking to bounce back from a trophy-less season at the Bernabéu.
With the many changes that have already been confirmed for next season, it's fair to say that football fans are in for an unpredictable, yet exciting season.
The countdown to the start of the 2013/14 Premier League season starts now.
