Colchester forward Ian Henderson is beginning to attract interest after rekindling his career with the Us.
Henderson joined Colchester in January this year following a stint in Turkey's top-flight with Ankaragucu.
The 25-year-old has proved his versatility and ability for the Us, playing in both midfield and attack.
Now it is believed Colchester's resolve to keep the player will be tested by more than one Championship club in January.
Reading are thought to be keen, while Henderson's former club Norwich - where he began his career - are also believed to be interested.
Henderson's current deal with Colchester expires at the end of the season.
