The Switzerland-based body will confirm the verdict at 10:30 local time (08:30 GMT) on Monday, it said in a statement on Friday.
City’s hearing at CAS began on June 8 and concluded two days later, with proceedings having been conducted by video call.
In an interview with HLN, star midfielder Kevin De Bruyne suggested he might be happy to stay at City in the event of a reduction to a one-year ban, although a two-year Champions League absence would force him to consider his options.
“I’m just waiting,” he said. “The club told us they are going to appeal, and they are almost 100 percent sure they are right. That’s why I’m waiting to see what will happen. I trust my team.
“Once the decision is made, I will review everything. Two years would be long, but in the case of one year I might see.”
