Maddox is regarded as one of the brighest young talents in the country after emerging on the scene at Bristol City.

The 14-year-old was promoted from the Under-14 set-up last season to the Under-18 side and he is highly-regarded at Ashton Gate.

A host of the Premier League's top guns were monitoring Maddox's situation at Bristol City and Chelsea have moved to lure the youngster to Stamford Bridge.

Maddox is believed to have agreed a four-year deal at Chelsea with Bristol City due a compensation fee for his services.
