Charlton are hoping to steal a march in the race for Exeter starlet Joel Randall.
Randall is also wanted by Swansea and Celtic but the south Londoners have lined up an opening move worth in the region of £300,000 for the exciting attacker.
The 21-year-old, who can play on both flanks and also centrally, has been Exeter's star performer this season, scoring eight goals and setting up five more in 26 games.
Charlton's first approach is expected to be knocked back but they are willing to test Exeter's resolve with an improved offer for the wide man whose contract expires next year.
