Chelsea appear to have emerged as one of the biggest beneficiaries of the extended three-week international break, with Xabi Alonso's side producing an impressive 5-1 victory over Bournemouth after using the pause to address tactical weaknesses and welcome back key players.
The commanding performance at Stamford Bridge suggested that the break arrived at an ideal moment for Chelsea, who had struggled defensively during the opening weeks of the Premier League season.
Before the international fixtures, Alonso was still searching for the right balance after introducing a back-three formation. Chelsea had conceded a league-high 12 goals, relying heavily on the attacking quality of Cole Palmer, Morgan Rogers and Joao Pedro to compensate for their defensive shortcomings.
A disappointing 3-0 defeat to Brentford exposed those weaknesses and highlighted the need for tactical adjustments.
Against Bournemouth, however, Chelsea looked considerably more organised, defending deeper, pressing in a different shape and adopting a more controlled approach to building attacks.
Joao Pedro, who scored twice in the victory, acknowledged the importance of the extended preparation period.
"The international break was a long time. We had time to work, to fix the mistakes against Brentford, and we got a great result," he said.
One of the biggest positives for Chelsea was the return of midfielder Moises Caicedo, whose presence brought greater stability and control to Alonso's system.
The Ecuador international had played just 14 minutes as a substitute before Saturday after suffering a recurrence of a calf injury during a brief appearance against Brighton.
His ability to recover possession, dictate the tempo and provide defensive protection made an immediate difference against Bournemouth.
Alonso was particularly enthusiastic about having the midfielder available again.
"Wow, I couldn't wait to have him back to be honest because with Moi on the pitch everything looks more in place," the Chelsea manager admitted.
"He is so important and we want to have him around. It was very good news."
Chelsea also welcomed back Joao Pedro, who leads the Premier League for goal involvements this season with eight, comprising five goals and three assists.
Marco Palestra and Emmanuel Emegha were also available, with both named among the substitutes.
Cole Palmer was another Chelsea player who appeared refreshed following the international break.
The England international withdrew from Thomas Tuchel's squad but recovered sufficiently to complete the full 90 minutes against Bournemouth.
Palmer spent part of the break on holiday while following an individual rehabilitation programme with a private fitness coach.
He also signed an improved contract extension upon returning to Chelsea, providing another positive development for the club.
With no international commitments, Palmer joined approximately 16 senior Chelsea players, alongside academy prospects, for an extended period of training.
That gave Alonso a valuable opportunity to work directly with much of his squad and introduce tactical changes without the usual disruption of international fixtures.
Chelsea's preparations included a behind-closed-doors friendly against Championship side Portsmouth, which ended in a 2-0 defeat.
Although the result attracted criticism, the match was primarily viewed internally as a training exercise rather than a competitive fixture.
Caicedo and other players returning from injury were given limited minutes, while several academy prospects featured.
The coaching staff also used the game to experiment with tactical adjustments and different combinations.
Away from the training pitch, Alonso dedicated considerable time to what he described as "office work".
That preparation reportedly involved analysing previous performances, identifying weaknesses and studying upcoming opponents.
The benefits were evident against Bournemouth, particularly in Chelsea's attacking set-piece routines.
The Blues' fifth goal came from a cleverly designed free-kick involving Palmer and Jordan Henderson.
Palmer shaped to shoot before Henderson curled the ball into the top corner, completing a routine developed by new set-piece coach Austin MacPhee.
The move reflected Alonso's determination to make Chelsea less predictable and more effective in attacking situations.
Improving their offensive output remains a major priority after the club's disappointing 10th-place Premier League finish last season.
Chelsea also benefited from having significantly fewer players away on international duty than several of their title rivals.
Only 10 Chelsea players represented their countries during the break, compared with 18 from Manchester City and 17 from Arsenal.
That allowed Alonso to work with a relatively settled group while other Premier League managers faced greater disruption.
Chelsea did suffer an injury setback, with winger Jamie Gittens sustaining an ankle problem while representing England Under-21s. He is expected to be sidelined for several weeks.
However, several rival clubs experienced more significant injury concerns.
Arsenal lost regular starter Christos Tzolis, while Manchester United saw Noussair Mazraoui and Patrick Dorgu suffer injuries.
Liverpool have also been forced to cope without Cody Gakpo, Alexander Isak and Dominik Szoboszlai.
Meanwhile, Chelsea players including Valentin Barco, Estevao Willian, Jorrel Hato and Geovany Quenda gained valuable playing time with their respective national teams.
The combination of additional training sessions, improved fitness and fewer international disruptions appears to have worked in Chelsea's favour.
Despite the clear benefits, Alonso admitted that the three-week international break felt excessive.
When asked about its duration, the Spaniard described it as "too long", although he acknowledged that Chelsea had made productive use of the time.
"We have had time for everything, to analyse what we have done in this game, what's coming and working with some players, recovering some players. We have used the time properly," he explained.
Chelsea's emphatic victory over Bournemouth provided encouraging evidence that the tactical work undertaken during the break is beginning to pay off.
The return of key players, greater defensive organisation and improved attacking variety all suggest Alonso is making progress in shaping his team.
However, one convincing result is not enough to establish whether Chelsea have permanently addressed their early-season problems.
The challenge now is to maintain that improvement against stronger opposition and demonstrate consistency over a sustained period.
For Alonso and Chelsea, the international break may ultimately prove to have been a turning point in their Premier League campaign.
