Los Blancos officials are far from happy with their current options up front and they are tipped to make a fresh assault on long-term target Sergio Aguero in the summer.
The Argentine striker is far from happy at Etihad, and he would jump at the chance to return to Madrid, where his son is currently residing.
Back in September, Aguero admitted that he had only joined City because Real Madrid had failed to make a bid for his services, and he remains keen on a move to Santiago Bernabeu.
It remains to be seen whether Manchester City will be prepared to sell in the summer, although they might not be able to resist a big money offer from los Blancos.
Sergio Aguero has scored a total of 32 goals in 57 Premier League matches for City, with his goal against QPR on the final day of last season proving crucial for the league title.
