So it's clear that Man City could do with some reinforcements up front, and here are five options they should consider.
1 – Luka Jovic – Eintracht Frankfurt
Jovic as emerged as one of Europe's most lethal strikers this season after forming a devastating understanding with Ante Rebic and Sebastien Haller.
The 21-year-old has scored 22 goals this season, propelling his side to the cusp of the Champions League places and into the Europa League quarter-finals.
He also became the youngest player in history to score five goals in a single Bundesliga match in October, in a 7-1 win against Fortuna Dusseldorf.
City have been heavily linked with the £40m man but will face stiff competition from Barcelona for his signature.
2 – Joao Felix – Benfica
Another player City will have to battle to sign is Benfica's Joao Felix, otherwise known as Europe's hottest talent.
Felix has burst onto the scene in Portugal this season, scoring 10 goals in 18 league games, at just 19 years old.
A versatile attacker who can play out wide or through the middle, though his preferred position at the moment seems to be playing as a second striker.
Felix's talent is undeniable and the race for his signing looks set to be the transfer saga of the summer as practically all of Europe's elite clubs are circling, with Juventus looking the favourites to meet his massive €120m release clause.
3 – Memphis Depay – Lyon
While Memphis' time at Manchester United was a marked disappointment after such initial hype it's impossible to deny that he has matured into a brilliant striker at Lyon.
While not the most prolific of goal-grabbers he brings a lot more to a team, with his skill, hard running and intelligence leading to lots of goals.
In 106 games for Lyon he has directly contributed to 74 goals, with 35 strikes of his own and 39 assists.
He's also the leading man in a resurgent Netherlands side.
The 25-year-old has been touting in the press how he would welcome a return to England and City could be the perfect place to prove the doubted across town wrong.
It also wouldn't be the first time City have swooped for a former United striker.
4 – Lautaro Martinez – Inter
A lot of hopes are pinned on 21-year-old Lautaro Martinez, for both club and country, as he's rated as one of best up and coming young strikers.
The Inter forward has fought his way into a regular starting position this season after several impressive performances off the bench, including scoring the last minute winner against Napoli.
Not afraid to take on pressure or responsibility Martinez also scored a winning penalty in the Milan derby recently.
It looks as though he has a big future ahead of him and what better place to fulfil it than City?
5 – Leroy Sane – Man City
Perhaps City don't have to splash the cash on a new centre-forward at all as Leroy Sane could be a viable option for the spot.
The usual rapid winger was deployed up-front by Joachim Low in Germany's recent victory over the Netherlands and the City man played brilliantly.
His constant, clever movement was a nightmare for a defence containing Virgil van Dijk and Matthijs de Ligt to handle and he scored the opener with a brilliant finish.
Sane has often been compared to Cristiano Ronaldo for a number of attributes and maybe another way he could replicate him is by adapting into a centre-forward.
It would save City big money on a transfer fee.
City also have plenty of talent at youth level such as Lukas Nmecha, Lorenzo Gonzalez and Nabil Touaizi who may make the step up.
