Thomas Tuchel's Chelsea admission should be warning for Liverpool and Man City

Chelsea have won their last four games in all competitions by an aggregate scoreline of 15-1.

The only goal they have conceded in October was a penalty against Southampton at the start of the month, and they have bounced back from consecutive defeats by Manchester City and Juventus in style.

The Blues recorded the biggest victory of Thomas Tuchel's tenure with a 4-0 win over Malmo on Wednesday, only to smash that record three days later with a 7-0 drubbing of Norwich City.

The remarkable result against the Canaries was even more impressive given Tuchel did not have forward duo Romelu Lukaku and Timo Werner at his disposal.

And while Manchester City were impressive in their 3-1 win at Brighton & Hove Albion later on Saturday, there can be no doubt Chelsea are the team setting the pace in the title race at present.

Thomas Tuchel has led Chelsea to the summit of the Premier League table

With a two-point cushion at the top of the table ahead of Liverpool's trip to Manchester United, Tuchel's side have already ticked off challenging clashes with the Reds, Tottenham Hotspur and City in their opening nine top-flight games.

However, what makes the German such an expert operator is the meticulous preparation he commits to every fixture, regardless of the strength of the opposition.

He may be a remarkable tactician who masterminded a Champions League triumph just four months into his time at Stamford Bridge, but Tuchel approaches each fixture with humility and underestimates no opposition.

The former Borussia Dortmund and Paris Saint-Germain manager is fully aware Chelsea were heavily fancied to beat Southampton, Brentford, Malmo and Norwich, yet this does little to alter the focus at the club's Cobham base.

"I don't want to get carried away too much because we play now four times in a row as favourites and I like the way we approach these games," said Tuchel after Saturday's jaw-dropping victory.

"It's a humble approach and it's an approach where we set our standards and we push ourselves and we play all in every match and are not distracted by the role which we are maybe seen in before the match."

The humility Tuchel is imprinting on his squad will serve Chelsea well in the knowledge that dropping points against middling or bottom-half teams could prove fatal in a hotly-contested title race.

Liverpool and City may have shared the last four Premier League titles, but their duopoly is facing its biggest challenge in years thanks to Chelsea and their manager.
