Colchester United forward Macauley Bonne has signed a new two-year contract with the League Two club.
The 20-year-old has scored 13 goals in 62 appearances, 22 of which were starts, since coming through the U's youth system.
Bonne has agreed a new deal a day after fellow forward Sammie Szmodics signed a new contract and defender Luke Prosser joined after his Southend release.
Gilbey joined League One champions Wigan for an undisclosed fee on Tuesday, while Moncur moved to third-tier play-off winners Barnsley for a fee believed to be in the region of £500,000.
Bonne told the club website: "The club pulled me in after the season finished and said that I had worked hard and deserved this new contract and it was an easy decision to sign.
"I was more than happy to continue my time here."
