RONNY DEILA is stepping up his plans for the transfer window re-opening at the end of this month.
And a couple of Scandinavians look set to figure prominently in the comings and going from Celtic Park.
Talks with John Guidetti and his agents to get the hitman to convert his loan move to a permanent contract are being conducted almost on a daily basis.
But, while the Swede is being offered the chance to stay, Jo Inge Berget appears to be on his way out as room is made and wages freed up for more new recruits.
Guidetti has quickly become a hero of the Hoops fans, scoring 11 rapid-fire goals, despite the delay in his signing ruling him out of Europa League games to the knockout round stage.
Deila would like nothing better than to see the striker - again a target for Marseille - commit long-term to the Parkhead club, and revealed he is constantly on the case.
"We talk together a lot, John and me," said the manager. "Hopefully, we can are going to get an agreement. But, it's not easy, with players and agents.
"I think it would be a good choice for him and I think he wants it. But, there are many people (involved) in a decision like that."
By contrast, Norwegian winger Berget was thrown into the side for the Champions League qualifier against Legia Warsaw in Poland within hours of joining Celtic on loan from Cardiff in July.
But, the 24 year-old -who previously played under Deila at Stromgsgodset - has failed to fire in the Hoops. Berget was on the bench last midweek for the SPFL game against Partick Thistle but did not get on.
He did not even make the list of subs at Motherwell, and the last of his eight appearances was as a late sub in the 1-0 home win over Dinamo Zagreb on October 2.
Celtic hold an option to buy Berget, but are not planning to exercise this, and he looks set to head back to Wales next month.
Deila revealed: "Jo Inge's loan contract finishes in January. We have not decided yet. But I think Jo Inge needs playing time and, therefore, he will look for other choices."
Deila had initially said he was not in favour of loaning in players, but felt it was appropriate during his first transfer window because he was still assessing what he had and what he needed.
Wakaso Mubarak is another of the loan signings brought in last summer, and the Ghananian winger is ready to remind everyone what he can bring to the side. He scored on his debut for the Hoops in the 2-2 draw with Salzburg in Austria.
But an illness has kept him out of action since he hammered in a spectacular goal for his country during last month's international break.
Deila put him on the bench at Motherwell and could play him in Zagreb on Thursday.
The manager confirmed: "He is 100 per cent again after his illness."
