Atletico Madrid are reportedly keeping tabs on Fernando Torres, Xherdan Shaqiri and Lukas Podolski ahead of a potential transfer splurge in January.
Mario Mandzukic has risen to the challenge of replacing Diego Costa as Los Colchoneros' main striker, but Coach Diego Simeone is keen to ease the workload on the Croat.
With Alessio Cerci nor Raul Jimenez convincing the Argentine trainer, Atleti could be set to snap up another attacker once the transfer window reopens next month.
The first name on the radar, according to AS, is Torres, a former fans’ favourite at Vicente Calderon, although the out-of-favour Milan loanee's wages could pose a stumbling block in any negotiations.
The newspaper also claims that the champions' sporting director Andrea Berta has already initiated contact with Shaqiri's brother and agent Erdin, aware that the Bayern Munich winger's contract expires in 18 months' time.
Last of the big names is Podolski, who is believed to be eyeing up a departure from Arsenal during the winter. The German World Cup winner is out of contract at the end of next season.
However, there seems to be more scope for Podolski's arrival, with the Gunners maintaining an interest in Cerci.
Galatasaray's Bruma is another player reportedly being considered by Atleti, as Simeone is keen to find a player who can successfully fill the role undertaken by David Villa last season.
