Celtic's chances of signing Patrick Roberts ahead of their final Champions League qualifier suffered a major blow when the winger was included in Manchester City's travelling party for a training camp in Catalonia.
Celtic are hoping to re-sign the 20-year-old on loan following a successful 18-month spell in Glasgow and Roberts is believed to be keen on a return.
One of the player's representatives, former St Johnstone and Hearts player Allan Preston, had admitted he expected his immediate future to be resolved last week but City listed Roberts in a 25-man party which landed in Girona on Monday.
