The key to getting Marchbank to the Blues

Greater Western Sydney defender Caleb Marchbank officially requested a trade to Carlton earlier this month. However, now comes the hard part with the two clubs needing to negotiate a trade for the youngster.

The Blues have stated that they will not part with their first selection in the National Draft, which is pick No.5, however, the Giants are keen to pursue a high draft pick for the former top-10 pick.

Channel Seven’s Sam McClure reports that Giant James Stewart could be sent to Carlton to sweeten the deal for the Blues.

The 22-year-old has played just 18 games in three years at the Giants, with the 198cm goal kicker unable to secure a regular birth in the starting side.

If Stewart is offered up, the Blues may be more willing to part with their top-10 selection.

To get the deal done, Carlton would then need to send pick No.5 to Greater Western Sydney, while the two clubs may also negotiate an exchange of later draft picks.

Marchbank has managed just seven games with the Giants since being selected with pick No.6 in the 2014 National Draft, due to an injury interrupted start to his career.
