Danny Cowley revealed the emerging Blues defender is the subject of a swathe of interest from National League sides, who want to sign the academy product on loan next season.
Those displays in a struggling Terras side who were eventually relegated caught the attention of a host of potential suitors.
The Londoner insisted, however, Mnoga will first get the chance to impress him before heading off anywhere else.
Cowley said: ‘The aim for Haji is to try to break through to the first-team squad or, even better, the starting XI.
‘He did really well at the back end of the season at Weymouth.
‘We were obviously watching his games so we know how well we did.
‘Having said that, we wouldn’t have even needed to watch his games, because I’ve taken so many calls from clubs in the National League who want him next season on loan.’
Mnoga has spent much of the close season away on international duty with Tanzania, where he’s been involved in Africa Cup of Nations action.
Cowley added: ‘He’s been away with Tanzania and he’s been out playing games with a tough programme for them. That’s good for him.
‘So he will come back for pre-season like everyone else and we will see how he’s progressed, before making a decision about the path forward for him.’
