A day after club great Frank Lampard was shown the door by Chelsea, Thomas Tuchel has been confirmed as the new head coach at Stamford Bridge.
Having departed Paris Saint-Germain in late December, the highly regarded tactician will now continue his coaching career in England.
Former Borussia Dortmund boss Tuchel won two straight Ligue 1 titles and steered PSG to the Champions League final last season, yet ownership decided the time was right for a change in the French capital.
Mauricio Pochettino's status as a free agent arguably persuaded PSG to act fast and the boot is now on the other foot for Tuchel, whose availability has allowed him to step straight in at Stamford Bridge.
FROM PARIS TO LONDON
There was little Christmas cheer for Tuchel, who left PSG with a record similar to his predecessor in the job - Unai Emery. Both recorded an average of 2.37 points per game in Ligue 1 - tied for the best in club history.
The German tops the list when it comes to top-flight win rate at 75.6 per cent (62 wins from 82 games), though that number dips slightly when taking into consideration all competitions, albeit only down to 74.8 per cent (Emery's was higher, at 76.3 per cent).
Like Lampard, Tuchel lost his job on the back of a convincing home win. PSG thrashed Strasbourg 4-0 in his final game and, while that result on December 23 left them third in the table, they were sitting just a point behind leaders Lyon.
Only Laurent Blanc (173 games) was in the PSG post for longer than Tuchel in the time since Qatar Sports Investments purchased the French club.
Tuchel averaged 2.67 goals per game in Ligue 1.
It helps to have a squad that contains stars such as Kylian Mbappe and Neymar, of course, though he was the first PSG boss to make it beyond the quarter-final stage of the Champions League, the one trophy that has so far eluded the owners.
An unconvincing start this term was enough to lead to change. Tuchel became the first PSG head coach to be fired during a season despite sitting in the top three of Ligue 1 since Antoine Kombouare, who lost his job during the 2011-12 campaign.
FAMILIARITY, PLUS A CASE FOR THE DEFENCE
Roman Abramovich made clear he has the "utmost respect" for Lampard in the statement released to confirm his departure. Still, there was no doubt left over the reason for making the change.
"We are grateful to Frank for what he has achieved in his time as head coach of the club," the statement read from Chelsea.
"However, recent results and performances have not met the club's expectations, leaving the club mid-table without any clear path to sustained improvement."
Chelsea have a home game against Wolves on Wednesday and Tuchel will get up and running by taking training on the eve of the match. He takes over a team in ninth place, though just five points off fourth in what is a congested league table.
It will be hoped the new man can get the best out of compatriots Kai Havertz and Timo Werner, two of Chelsea's big-money recruits in the previous window who have yet to fire.
However, Tuchel will also need to tighten things up at the back, particularly on the road. At PSG, his teams conceded 0.81 goals per game, while it should be noted they leaked just six in Champions League action in 2019-20.
Since the start of the previous season, only Newcastle (54) have conceded more away goals in the Premier League than Chelsea (50).
They kept a clean sheet in just 17 per cent of their away games under Lampard; among those to have taken charge of 10 or more such fixtures in the competition, this is the lowest percentage of any Chelsea boss.
Tuchel will, of course, be able to call upon his old PSG captain Thiago Silva in trying to mastermind a defensive revival.
There will also be an expectancy to improve the team's fortunes against their major rivals, too.
Since August 2019, Chelsea have won just 15 points against fellow 'big six' sides, a joint-low tally alongside Arsenal. During that run, they have scored 17 goals and conceded 28 times.
At least Tuchel understands the demands of working for owners with lofty expectations. There is still time to turn this season around but, like his most recent Stamford Bridge predecessors, he will be expected to produce instant results.
