Liam Scales has been tipped for a contract extension at Celtic by Brendan Rodgers.

The Irishman has played the last 15 games for the Scottish champions after getting a chance due an injury crisis at centre-back.

And the defender, who has 18 months left on his deal at Parkhead, is someone the Celtic boss is keen to get tied down on a longer deal.

Rodgers said: " I think it’s something that I’m sure the club and his representative will look at.

"It doesn’t sit with me so well when players are going down to the final stages of their contracts.

"I think you only need to look at the fact that I’ve chosen him to play very consistently in games. There are also players back now fit that are pushing him but he’s still performing to a high level.

"As I said to him, it’s about consistency. Keep showing that you can be consistent and stay focused. But there’s no doubt that he’s stepped in and done really well."

Meanwhile, Celtic striker Oh Hyeon-gyu and the rest of his South Korean teammates have been given the green light by Jurgen Klinsmann to spend time with their girlfriends and families during their World Cup qualifying camp this week.

The 22-year-old headed off to Asia in fine form after netting a double in Celtic's 6-0 romp against Aberdeen on Sunday and he also scored a late winner against St Mirren at the start of this month.

South Korea face two huge games this week in World Cup qualifiers at home to minnows Singapore and then away to China at Shenzhen.

But relaxed manager Klinsmann has adopted an unusual policy for the ties, with the former Germany World Cup and Euros winner and manager insisting he won't keep Oh and co locked up in their base.

He said: "I've told them all if they want to visit their girlfriends or their family, fine, no problem. They are all adults.

"As long as they are here for training, meetings and meal times. There is no problem as long as we win the games.

"As a manager, it is important to understand the environment in which the players grew up. Working with young people is interesting.

"But there is a difference between the young people of my era and the young people of today.

"All players must have a sense of ownership and responsibility. Football is a sport played by players themselves - the manager absolutely cannot do it for them.

"The atmosphere in the camp is really good."
