He has not received any request from Spurs' boss Andre Villas-Boas to rest the winger and he looks certain to start against Bosnia in Llanelli.
Coleman said: "Sometimes you see a player from afar and think he is good. But when you work with them, you see something more.
"In training, Gareth has done two or three things that took our breath away. (Ryan) Giggsy used to do it, but there have not been too many others.
"We would come away with Wales and Giggsy would do something and we would just laugh because we all knew he was on another level.
"We are in the presence of something similar, something special, with Gareth. Look at him, he's six foot plus, he's a racehorse, but he has this amazing ability as well."
