Celtic have opened talks over an improved contract for striker Gary Hooper.
Hoops manager Neil Lennon revealed Celtic had begun moves to keep hold of the 24-year-old Englishman, who has been linked with a move to Barclays Premier League newcomers Southampton after hitting 29 goals last season.
Lennon told STV: "We had a preliminary meeting with his agent last week and it was very cordial.
"It went very well and we made it clear that we want Gary to stay.
"Gary likes it here and he's happy here. He's had such a good season and he's such a good player that no doubt there'll be clubs in for him, but we'll try and resist all offers that come our way."
Following Celtic's 2-0 defeat to Norwich in Adam Drury's testimonial match at Carrow Road on Tuesday night, Lennon added: "Gary is one of our best players, and quite rightly so, he will be looking to get a wage increase, and we don't have a problem with that."
Celtic are also on the trail of Norwegian midfielder Markus Henriksen from Rosenborg.
"We have not made any contact with the club yet, but he is a player we admire," said Lennon.
"We have got a bit of work to do with trimming the squad before we can possibly even think about bringing players in, but we have targets for three or four positions.
"We do like the player, but I do not know if we will be able to get a bid going in the next few days or not."
