Celtic are eyeing Arsenal fullback Carl Jenkinson.
Hoops boss Neil Lennon is searching for a new right-back following the exits of Mikael Lustig, Jeremy Toljan and Cristian Gamboa.
Jenkinson, 27, played just eight times for the Gunners last season but is keen to play more first-team football.
He does not appear to be in Unai Emery's plans, despite a shocking lack of defensive options at the Emirates, says The Sun.
Lennon had identified George Baldock as one of his top targets for the position, but Sheffield United are reluctant to sell the defender.
