Brazilian midfielder Anderson and Rio Ferdinand did both feature for the United reserves on Wednesday night against Oldham.
Gary Neville is also close to a return to action.
“The squad is looking really strong,” Giggs told the cub’s official website.
“We’ve got Rio to come back in, Nev hasn’t played yet, and Anderson is back too. So it’s looking really good.
“It’s a headache for the boss, but one he would rather have than to be struggling for players.
“We’ll need everyone because it’s a long season. The manager realises that.”
