The focus may have been on Manchester last season, but the title went to the capital and the run-in was a battle between two London clubs.
Lukaku finished second to Golden Boot victor Harry Kane of Tottenham last term.
It means he can freely switch formations from 3-5-2 and 4-3-3 this season, depending on injuries and opponents.
City certainly haven't let up in the transfer window with numerous players going in and out of the Etihad Stadium in the summer months, with a number of familiar faces been replaced by a new roster of new faces.
There has been much debate over whether Sergio Aguero is Pep Guardiola's man up front but he still managed 20 goals in 31 Premier League starts past year and looks the number one option going into the new season.
"We were focused on the goals that our striker was scoring".
Whether he plays in a back four or a back five, Walker will provide constant attacking support and still come back quickly to maintain defensive shape when City don't have the ball. Barcelona is expected to offer up to £120 million for the 25-year-old Brazilian.
City also look stronger on paper.
The full back position has been another problem area and Kyle Walker, signed from Spurs, is a clear upgrade at right back and France global Benjamin Mendy from Monaco an improvement on the opposite flank.
Sergio Aguero, Gabriel Jesus, David Silva, Kevin de Bruyne, Samir Nasri, Leroy Sane, Bernardo Silva and....to lesser extents.... Any improvement in their away form this term may take a while to materialise - after the Blues, their early road trips take in Tottenham, Liverpool, Everton and Manchester City before November's visits to Southampton and Bournemouth.
There are question marks over Chelsea which may only be answered by the end of the transfer window.
Since taking over the reins at the Manchester club, the Portuguese manager has spent over £300 million and meticulously cherry-picked his signings.
The 24-year-old signed for Chelsea from Real Madrid in July for a reported fee of £58 million and, in an interview with Spanish newspaper Marca, admitted there was a degree of pressure attached to his fee.
Pep said goodbye to all three of the aging full-backs and brought in young players to fill a position of clear need.
Arsenal - It will be another season of pain for Arsenal with possibly more protests over Arsene Wenger.
Full-backs have been key to Guardiola's coaching career, and last season the four on his squad simply couldn't provide what he was asking of them.
United drew 10 of their 19 home league games as they registered the top-flight's seventh-best record in front of their own fans.
Tottenham - It looks like a mistake that it hasn't strengthened its squad, though perhaps it still will before the season kicks off. Spurs had a terrific campaign last season and had it been any other season they would have won it.
