Chelsea have been in great form recently after bouncing back from their shock defeats to Everton and Basel three weeks ago.
A 1-0 Premier League loss to Everton was followed up by an even worse Champions League defeat at home to Swiss side Basel.
The results meant it was an unhappy and worrying time for Chelsea fans who thought that the return of the their god, Jose Mourinho, would only bring about success.
And they may still be correct after the Portuguese man turned the side's fortunes around and guided them on a five-game unbeaten run.
2-0 wins over Fulham in the league and League One side Swindon in the Capital One Cup was followed by a determined point against apparent title rivals Tottenham Hotspurs at White Hart Lane.
A fantastic 4-0 European away win over Steaua Bucharest and a battling 3-1 victory over Norwich, means the Blues are set up nicely ahead of three weeks that could shape their season.
Chelsea have five matches over the space of 14 days after the international break, with three tough Premier League games, an away Champions League tie and a Capital One cup London derby.
If all goes to plan for Mourinho this month could be key to setting the team up ahead of the Christmas run in.
October 19th will see Chelsea welcome Premier League new-boys Cardiff City - a game which should be easily converted into three points.
But on Sunday October 27 Chelsea host their most important home match of the current season.
Title rivals Manchester City travel to Stamford Bridge after suffering a disappointing 3-2 away defeat against Aston Villa.
With the gap between the sides in the league only at one point this will be the perfect chance to push back one of the fellow contenders.
With one win and one defeat their first two european games of the season, the away game to German side Schalke is crucial.
A win is not necessarily needed, but avoiding a defeat is.
Premier League sides have taken the League Cup a lot more seriously over the last few seasons.
Previously the cup was seen as a chance to blood the youth team rather than actually try and win the trophy.
But now it is seen as an early chance to prove to their rivals that they mean business and have a trophy in the cabinet before March.
Chelsea face Arsenal at the Emirates in the next round on October 29 and just two days after, the league clash with City.
Luckily for Chelsea, their spending over the summer has enabled Mourinho to have a large squad with strength in depth.
This will be the perfect opportunity for fringe players to impress and prove they deserve a place in the league side.
It is also an opportunity to gain a second win over a rival in a matter of days - if they beat City that is.
Creeping into early November, the Blues travel to St.James' Park on November 2 to complete their busy fortnight schedule.
This game in itself will not be easy. Newcastle have begun the season in good form and will not be push overs.
Whatever comes from these five games for Chelsea it will no doubt have a huge effect on their season.
