Celtic boss Neil Lennon is desperate not to lose Gary Hooper.
Southampton are keen to bring the Englishman to the Premier League.
Lennon said: "He's a player I like and he's done really well here.
"We'd like to tie him down for a bit longer if we could.
"He's really enjoying it here and at just 24 he's still got plenty of progress in him.
"He knows he has a big season ahead of him in terms of Europe and the domestic scene and he wants a wee taste of that again.
"We met his reps at the end of May so I'd assume talks will continue in the next few weeks."For all the latest football news go to tribalfootball.com.
