A select round-up of the latest news involving Mark Warburton's Glasgow Rangers and Brendan Rodgers' Hoops.
The pair moved to Parkhead from Tannadice, and the Evening Times reports that Ciftci, in particular, is unlikely to have a role to play under Brendan Rodgers.
The former Hoops defender admitted that he had spoken to the club and turned them down before they ultimately went with Brendan Rodgers.
"They spoke to me several times before but I had other clubs this summer who met me at the same time," he told The Scottish Sun.
"I've had opportunities to go abroad but I wanted to come back to the Premier League."
Nir Bitton has confirmed that he would be willing to play in the second-leg of Celtic's Champions League third qualifying round tie with Astana on Wednesday even if he is not fully fit, The Scottish Sun reports.
The midfielder limped out of the pre-season game against Barcelona at the weekend due to an ankle injury, but insisted that he will take to the pitch at Parkhead if asked.
"If it was my decision then I would play. But it's not my decision," he told The Scottish Sun.
The summer signing is yet to open his account for the Hoops, and his senior partner has offered him so advice.
"Sometimes when you are under pressure you end up thinking too much about it. If you relax it just comes naturally," he told the Evening Times.
Rangers' James Tavernier
Former Celtic striker Andy Walker has been full of praise for the business that Rangers have done this summer but taken a swipe at defender James Tavernier by claiming that while he has been prolific going forward, he needs to work on the job he is in the side to do, Sky Sports reports.
"James Tavernier catches plenty of headlines for his extraordinary goalscoring from right back but as he showed in the Scottish Cup final against Hibs, he can be very weak at defending," he told Sky Sports.
Lee Wallace has told the Daily Record that he has already seen enough from summer signing Joey Barton to believe that he will back up the comments he made about being in a different league to Scott Brown.
"Yes, I do feel that. In the three weeks I've known him I feel his passion, I feel his energy," he told the Record.
