Having fought to sign Alvaro Morata from Real Madrid, Juventus were stunned when the Spanish striker picked up a knee injury and they may look for another attacking recruit.
Juventus battled reported competition from Arsenal and Liverpool to sign Morata for £15.8 million, but the new man damaged his knee in his first training session with the Bianconeri.
It is suggested that Juventus will make contact with Chelsea in an attempt to sign Belgian international marksman Romelu Lukaku on loan.
That could be a tough task for the Serie A side because Lukaku is wanted by a number of clubs, including Everton, where he excelled last term, and could also stay at Chelsea this season.
Chelsea have rebuffed previous attempts to agree a loan and are said to be only willing to consider an outright sale if the price is right.
Last season's Serie A runners-up Roma reportedly saw a loan approach turned down and Juventus would be unlikely to enjoy any greater success.
Eto'o is still searching for a new club since his contract at Stamford Bridge expired and he is said to be keen to stay in Europe.
It is believed that Juventus would offer a one-year contract and would hope to reduce the Cameroon international's wage demands, which currently are too high.
