The 24-year-old's proposed world-record move to Real Madrid appears to be nearing a conclusion after Spurs boss Andre Villas-Boas said the deal could happen "very soon".
And, despite the continued uncertainty over his club future and series of niggling injuries, Coleman has included Bale in his squad to face both Macedonia and Serbia next month and expects the winger to play some part.

"We know what is going on and it is not easy for him, or for Tottenham. But he is very much part of our plans.
"With Gareth, there is obviously a lot going on mentally, but to have him is a boost for us.
"Maybe he won't be able to finish 90 minutes, but if he can play some part then it is a big boost."
Asked how he expected Bale to handle the attention that is currently being heaped upon him, Coleman backed the former Southampton man to cope with the situation.
"He has got to take it in his stride," the Wales boss added. "He is in that pressure-cooker situation where the spotlight is on him.
"It is difficult for Tottenham too in that people are speaking about one of their players. He is still their player.
"It is public knowledge that something could be happening. It’s not been easy for him. But he is a very unassuming lad. He is very grounded."
