Initial estimates suggested he'd be sidelined for around two months but Coleman's rapid recovery saw him back in a Blue shirt quicker than even he expected.
"I surprised myself to be honest," he told evertontv. "I was back training on the Monday and had a really good week. Obviously I was trying to impress the manager, he saw fit to put me in and I was more than happy to play.
"It was very frustrating to get injured when I did," he added. "I was really enjoying that match against Villarreal, it was close to half-time and then I got that dirty tackle.
"It was disappointing to miss the first two games of the season, but I was suspended for one of those so only really missed one league game through injury if you want to look at it positively.
"When it happened I thought it was broken but you always panic at that stage. I calmed down a bit but it was badly swollen and bruised and we thought I would be out longer.
"There was no exact timescale but thankfully I healed quickly and I wasn't out for long. I am generally a quick healer and I was itching to get back so I listened to the medical staff and did exactly what they said."
