Despite enduring a shaky period in their season in September, Chelsea have since managed to turn their fortunes around as they sit just a single point from the top of the Premier League table.
A 3-0 beating handed out by fellow title rivals Arsenal – which was followed by a 2-1 defeat to Liverpool – at the end of September saw new manager Antonio Conte look to spark a change in his side in order to keep them amongst the chasing pack come the end of the season.
Following the Arsenal defeat, the former Italian national team boss sought to change his side's system by employing a 3-4-3 formation, and the results are already paying dividends.
Since the back-to-back defeats, the Blues have gone on to record victories over the likes of Hull, Leicester, Manchester United and Southampton, and what's most impressive is that they have done so without conceding a single goal and bagging 11 in the process.
The new system has seen them suffer in terms of possession, recording just 51% over the past six games, but that doesn't seem to have hurt them much as they have allowed only eight shots from their opponents during this impressive run.
They are also more prominent in the tackle, with the side making 83 over the last four games, which is an improvement on their first six matches.
Conte is known for his fiery temper on the sidelines and on the training ground, but it would appear that he has had no problems in getting his instructions across to his players as they close in on the top of the table.
However, Chelsea's next four fixtures will prove a real test. Starting with a tough meeting with Everton on Saturday, they will take on a tricky Middlesbrough side before a heavyweight double bill against Spurs and Manchester City.
But unlike their fellow top four contenders, the Blues will be unburdened by European action, giving them more time to rest and recover between games.
The club will be desperate for success this term, having been so abject for much of last season, and given the good form they are displaying at the moment, they are on course to getting themselves back on track.
