Celtic have completed the loan signing of Manchester City winger Patrick Roberts.
The 18-year-old - who cost City £12million when they bought him from Fulham in the summer - has joined Celtic for 18 months.
Celtic are also hoping to complete the signing of Turkey international Colin Kazim-Richards from Feyenoord, while Nadir Ciftci could be going out of Parkhead after Turkish side Eskisehirspor launched a bid to take the former Dundee United forward on loan.
Former Brighton player Kazim-Richards has arrived in Glasgow and told Sky Sports News: "I think I can bring a lot (to Celtic). We have to get the final details sorted then hopefully I can be in the green and white."
Meanwhile, Rangers and St Johnstone are understood to have agreed a fee for Michael O'Halloran to move to Ibrox.
The Glasgow club failed with two bids for the Saints wide man earlier this month but they are close to completing the signing of the 24-year-old after submitting an offer in the region of £500,000, which is subject to a number of clauses.
