Ivory Coast international Boubacar Sanogo is trying to win a move to Monaco.
Sango is available from St Etienne, who are keen to get him off their wage bill after two years of injury issues.
Celtic and Rangers had previously been keen on the 28-year-old but deals failed to materialise, whilst Stoke and Everton were also linked.
Now St Etienne are willing to let him leave and are happy to let him train with second division Monaco, who are enduring a horrible start to the new season as they are bottom with just one win.
"I am trying to come back from the injuries I have had these past two seasons, it has not been easy for me," he told skysports.com.
"St Etienne have never seen me play regularly for the past two seasons and it is normal for them to try to send me on trial, hopefully I will prove my fitness and earn a contract here."
