Carl Starfelt has been quarantining in London since Sunday according to the Daily Record.
Celtic only announced his transfer on Sunday but the defender should be available for the opening SPFL fixture against Hearts on July 31.
Transfer business has been complicated by travel issues related to the pandemic with Liel Abada the only new face in the Celtic side that drew 1-1 with Midtjylland.
The Daily Record reports:
Swedish international Starfelt completed his move from Rubin Kazan on a four-year deal. Record Sport can reveal the 26-year-old arrived in London on Sunday and is quarantining as per the rules of his arrival from Russia.
The centre back won’t be eligible for Celtic’s Champions League return leg with Midtjylland. However, providing there are no last-minute hold ups, the deal and international clearance should be in place for the trip to Tynecastle a week on Saturday.
With Kris Ajer now at Brentford and Chris Jullien in rehab Ange Postecoglou is short on options to play in central defence, compounded by Nir Bitton’s red card against Midtjylland.
Stephen Welsh and Dane Murray seem the most likely partnership to play in the return leg on Wednesday with Leo Hjelde the only other option.
On Saturday Celtic host West Ham in a friendly match with the trip to Tynecastle coming three days after facing Midtjylland in Denmark.
Kyogo Furuhashi left Japan for the UK on Tuesday which makes him doubtful for the match at Tynecastle.
