Former MK Dons midfielder Keith Andrews is to take up a full-time coaching role with the club this season.
Midfielder Gary Deegan has signed a new one-year deal at Southend.
John Collins says Leigh Griffiths has just as much chance of winning another Scotland cap by staying at Hibs as he would do if he went south.
The striker has impressed while on loan at the Edinburgh club and was voted PFA Scotland young player of the year by his fellow professionals on Sunday.
Parent club Wolves ultimately have the final say on his future with a one-year option on his contract at Molineux.
However, former Hibs boss Collins says the best option for the 22-year-old could be an extended stay in the SPL.
The former Scotland midfielder said: "From an international point of view, if he's playing in the SPL and scoring goals every week, then Gordon Strachan is going to be aware of him.
"I don't think it really matters where you are.
"If you are playing well and scoring a lot of exceptional goals, then there is a good chance the Scotland manager will have his eye on you.
"He's a good fit for Hibs. He's the main man, he's very comfortable and relaxed and he knows the team needs him and he knows the fans love him.
"He's in a comfort zone - but a good comfort zone.
"I think if he goes down south he will be outside his comfort zone and I wouldn't bet money on him being a huge success.
"He's got talent, he's a good football player and he's got self-belief, which is so important."
Griffiths made his international debut in a friendly against Luxembourg last November.
The views of Collins were echoed by Strachan's predecessor Craig Levein.
He said: "When you're the Scotland manager, you get advice from a lot of people, as you can imagine.
"You have to use your own judgement and I feel, this season, in my eyes, he has become more of a team member than he'd been previously.
"He's working harder and I think he is getting the rewards for that and Hibs are getting the rewards.
"I've no doubt, if he continues in the vein that he's going, that Gordon will have a look at him and he might get a few games coming up."
