Manchester City and Chelsea were both in the market for a striker ahead of the 2021-22 season.

Although Chelsea sealed Romelu Lukaku's return – for a club-record fee reported to be £97.5million – City were unable to break Tottenham's resolve and sign Harry Kane.

For a brief time towards the end of August, it seemed Cristiano Ronaldo would be heading to the Etihad Stadium. Yet City again came away empty-handed – Ronaldo, like Lukaku, returning to a former club as he joined rivals Manchester United.

Indeed, City were once linked with Lukaku, with the forward himself claiming he had turned down an approach in 2020. But Pep Guardiola's team have, so far, cast aside any doubts that a lack of an out-and-out striker would cost them dearly.

City looked set to be in a three-way title race earlier in the season, alongside Chelsea and Liverpool. Heading into their second top-flight match of 2022, they are 10 points clear of the Blues and 11 clear of the Reds.

City turned in a statement performance in a 1-0 win at Stamford Bridge in September and, while rumours swirl of impending approaches for Erling Haaland or Dusan Vlahovic, two of Europe's brightest striking prospects, it will be Guardiola's 4-3-3, false nine system that Thomas Tuchel must look to counter on Saturday.

Rom's return

It would be fair to say Lukaku's return to Stamford Bridge has not yet matched what was expected. Having led Inter to their first Serie A title in 11 years, Lukaku re-signed for Chelsea to much fanfare and, undoubtedly, as one of the most fearsome finishers in European football.

Lukaku's second Chelsea debut could hardly have gone better as he opened the scoring against Arsenal after just 15 minutes, putting his strength, pace and positioning prowess on full display.

Yet he has so far failed to hit his stride. His five league goals from 13 appearances ranks him behind Mason Mount and Jorginho (both six) in Chelsea's squad, albeit the latter has netted all of his from the penalty spot.

Lukaku's goal return has come from a total of 22 shots, the fifth-most in Chelsea's squad, at an average of 2.3 per 90 minutes played. However, his rate of scoring every 166 minutes in the league puts him top of Chelsea's squad in that metric.

But that has been another issue with his comeback. Lukaku has featured for just 828 minutes in the league, starting only eight times, with 12 team-mates accumulating more game time.

An injury sustained in a Champions League win over Malmo in October kept him out of action for several weeks and he subsequently contracted COVID-19.

Then, late in December after he scored in successive matches against Aston Villa and Brighton and Hove Albion, Sky Italia released an interview, conducted several weeks previously, in which Lukaku questioned Tuchel's tactics and suggested he could leave Chelsea.

Romelu Lukaku has not had the best start to his second Chelsea stint

Tuchel reacted strongly, dropping the forward for a pivotal clash with Liverpool on January 2, which finished 2-2. Lukaku apologised and returned to Chelsea's side for the first leg of their EFL Cup semi-final against Tottenham.

One of Lukaku's complaints was about how Tuchel has used him so far. 

Last season, playing typically in a 3-5-2 system at Inter, Lukaku averaged three shots, 1.5 attempts on target, 7.3 touches in the opposition box and 1.6 chances created per 90 minutes, across 36 Serie A appearances. But those figures have so far dropped to 2.4 shots, 0.9 attempts on target, 6.4 touches in the opponent's box and 1.5 chances created this term, with the forward deployed as a target man to combine with Mason Mount, Kai Havertz, Christian Pulisic and the rest of Chelsea's attack.

It is a role that does not seem to suit Lukaku best, though Tuchel has made it clear who the boss is.

False nines and a flying full-back

Chelsea and City have played 21 league games this season, but Guardiola's team have netted six goals more. They average one every 36 minutes, compared to Chelsea's 43, and have out-shot the Blues 391 to 320.

This is all without a recognised number nine but, as proved by their charge to a third league title in four seasons in 2020-21, City have cracked the code of having any player but a centre-forward lead their line.

Whether it is Phil Foden, Kevin De Bruyne, Raheem Sterling, Jack Grealish, Ilkay Gundogan, the magnificent Bernardo Silva or, occasionally, the man who wears nine, Gabriel Jesus, City have a wealth of stellar options to slot into that role.

Sterling and Silva, who has been in sensational form all season, lead the way with seven goals each. It is a testament to Guardiola's man management that the duo, who might have left the club in 2021, are in such rich form.

Man City do not have an out and out goalscorer, but do they really need one?

Riyad Mahrez – the only City attacker with a consistent position – has netted six. De Bruyne and Foden have added five apiece.

City share their goals around for fun, while three players (Sterling, Silva and Jesus) have had over 100 touches in the opposition box, with Grealish on 99. No Chelsea player has managed more than 76 (Mount). 

De Bruyne's 36 chances created is more than any other player in City or Chelsea's squads, while the Belgian is level with Foden and Gundogan for big chances created (six), with Mount the only Blues player able to match them.

Allowing whichever front five plays for City to flourish is Rodri, who has taken the mantle from Fernandinho at the base of midfield, and creative support comes from the superb Joao Cancelo.

He has provided four league assists from 22 chances created, which ranks him sixth in the competition for defenders, with his four big chances tied for fourth, behind Trent Alexander-Arnold (11), Andrew Robertson and Reece James (five), who is a big injury miss for Chelsea.

It is not just Cancelo's passing and crossing that supports City's attack, however, with the full-back registering fourth in the league, behind three club-mates, for total carries (380) and sixth for carry distance (3,867 metres). Thiago Silva is the sole Chelsea player to have a place in the top 10 for either statistic.

Finely balanced

While City seemingly have the edge heading into Saturday's contest, Tuchel found a way to thwart Guardiola's system last season.

City countered this with their aggressive approach at Stamford Bridge but only four months previously, Guardiola's men fell short in their first Champions League final – Havertz scoring the winner in a match that perhaps forced City to make their move for Kane.

Tuchel won all three of his encounters with City in 2020-21, though those matches are the only times he has beaten Guardiola, who won three of their five Bundesliga meetings.

Chelsea went toe-to-toe with Liverpool and came out with a point earlier this month, though if Chelsea are to rope City back in, they need their investment in Lukaku to pay off.

Should City's death by a thousand cuts prevail, Chelsea's title challenge might well and truly have bitten the dust.
