Bournemouth midfielder David Brooks, who began the 1-0 loss in Portugal last Thursday, missed Sunday’s 2-0 defeat in Denmark and will again be absent through injury against Norway.
Wales were already without a number of players including first-choice goalkeeper Karl Darlow, centre-backs Joe Rodon and Dylan Lawlor and key forward Harry Wilson.
As his side look for inspiration, Bellamy has pointed to his spell as assistant to Vincent Kompany at Burnley as a reason for optimism.
“You never truly get beaten and I’m sorry, it’s a cliche saying it, but it’s what you learn… how can you improve?” he said.
“I’ve been there as a player and I’ve been there as a coach. I went for a whole season only losing two games as a coach [at Burnley] to the next season only winning two games. That coach then [Kompany, who is now Bayern Munich boss], where’s he now? What’s he doing?
“But it was the moment when he wasn’t winning, that’s the coach you see now. That’s what I got to witness. So for me I’m always, yeah, keep working, keep going.”
