Maloney spent two spells with Celtic, but he has admitted frustration with his second stay at the club.
Speaking to Sky Sports, Maloney has admitted that his second spell with Celtic was frustrating, due to injuries preventing him from making a proper impact at the club.
The attacking midfielder said: “The second [spell] was really frustrating due to injury, and I just wish I was able to give a bit more on the pitch than I was able to.”
Maloney, now 32, started his career at Parkhead in 2000, before leaving to join Aston Villa in 2008.
He return to the Bhoys the following season, and stayed until 2011, when he signed for Wigan. He currently turns out for Chicago Fire in MLS, but it was in Scotland where he has spent his most successful years.
Five SPL titles, five Scottish Cups and three League Cups were picked up during his two spells at the club, but he never managed to reach the heights of his first spell when he returned north of the border.
Regularly playing full seasons in his first years, he only ever played more than 30 games on one occasion in his second four seasons at Parkhead, and he never reached the heights of his earlier goalscoring form.
When he left for Wigan he ended up winning an FA Cup, and rediscovering his impressive performance levels, but his frustrations with that second Celtic spell remain.
At 32 it is unlikely that he will now be given another chance to return to Parkhead for a swan song of sorts, and those injury problems that dogged his second spell at Celtic are sure remain in his thoughts as he now looks to end his playing career in MLS.
