Real Madrid have received a boost with Gareth Bale included in the Wales squad to face Spain and Republic of Ireland after a groin scan showed no sign of injury.
Bale went off at half-time in Madrid's 0-0 draw against Atletico Madrid in LaLiga last weekend and was left out for the surprise Champions League loss at CSKA Moscow on Tuesday.
Reports in the Spanish media claimed the injury was not serious and he would be available to face Deportivo Alaves this weekend, which Giggs revealed the 29-year-old expects to be the case.
"He had a little groin strain, but the scan has come back clear. He expects to be involved at the weekend so that's good," said Giggs.
Bale could then feature against Madrid colleagues including Nacho Fernandez and Sergio Ramos when Spain visit Cardiff next Thursday, but the Wales boss was unwilling to make any guarantees over his selection.
He said: "I think every player's motivation will be high for a number of reasons; playing for your country first and foremost, you're playing against a very good team, it's a chance to test yourself and it's at a different stadium.
"With Gareth playing in Spain there will be added motivation for sure.
"I think every player will want to be involved in this game because it's a fantastic game. It's my decision. I'll analyse the lads, what they're like when they turn up."
Ryan Giggs has named a 25-man squad for the international challenge match against Spain and the encounter against the Republic of Ireland.More info: October 4, 2018
