Roberts spent two-and-a-half years in Glasgow at the Hoops, winning three Premiership titles and playing a key role in the club’s ‘Invincible’ treble campaign.
Brendan Rodgers’ side had been linked with making a permanent move for Roberts but the England youth international wanted to try his hand at something new and decided to try his luck in Spain.
However, things haven’t gone to plan, despite Roberts setting up Girona’s winning goal away at Valencia in his first La Liga start.
Roberts has managed just three starts in total, and will come back to City in January, according to the Sun, with his future undecided.
Roberts cost City £12 million from Fulham back in 2015, but could Celtic come up with a deal to re-sign Roberts permanently?
