Deacon was one of the prominent stars as Sutton enjoyed a wonderful run in the FA Cup this season, and he showcased his talents against Arsenal.
The midfielder looked a constant threat in Sutton’s most recent match against the Gunners, and even hit the bar with a wonderful strike.
Deacon’s form has not gone unnoticed, and Forest are now believed to be willing to give the 25-year-old another chance in the Football League.
Deacon has previously represented both Stevenage and Crawley Town, but took the step into non-league football last summer.
The England under-19 international now looks set to depart Sutton in the summer, and Forest do face competition for his signature.
Fulham, Charlton Athletic, Cardiff City and Millwall are all also said to have an interest in taking Deacon.
Sutton are believed to be keen to offer Deacon an improved contract, but whether he will be willing to sign a new deal with so much interest in his services remains to be seen.
