For Aleksandar Kolarov, stepping out onto the Parkhead pitch will feel like an old boys' reunion.
Lining up for Celtic will be former Manchester City team-mates Kolo Toure and Scott Sinclair, while young Patrick Roberts - on loan but allowed to play against his parent club - will likely be on the bench.
Kolarov also recalls being impressed with Nir Bitton while the Israeli was on trial in Manchester.
And he reckons with players of that calibre in Celtic's ranks, as well as on-form striker Moussa Dembele, the Scottish champions can't be written off.
