John Hartson has confirmed that he has spoken to John Toshack and made himself available for a Wales return.
Hartson is available to add to his 51 caps
The 31-year-old striker announced his international retirement in February, but a summer move from Celtic to West Brom has prompted a rethink.
National manager John Toshack favours a speedier front line but he has welcomed the back-up that Hartson can provide.
"I spoke to John (Toshack) on Monday and said that if I'm needed I'm there for him," said Hartson.
"He was delighted with that. He doesn't want me to travel half-way round the world if I'm not going to play, but if there are injuries or suspensions then I am available."
Hartson's original decision to quit was prompted by a desire to see more of his children, but having moved closer to his native Swansea he has more time.
"If Wales need me they will give me plenty of notice, I'm half out of retirement," said the 6ft 1ins target man.
Hartson made his Wales debut in March 1995 in an away match against Bulgaria, and went on to score 14 goals up to his last appearance against Cyprus last November.
I made it clear to John that with the style we will be playing at times it would not fit in with the way he plays
"Hartson has done things in the right way, he phoned me to tell me that he was available again," said Toshack.
"That's great and we will consider him in the future, but I must say the lads who have come in have done well.
"I made it clear to John that with the style we will be playing at times it would not fit in with the way he plays, but I am happy that he is available and it does give me that extra option."
Liverpool and Wales front man Craig Bellamy was also happy to learn that he could partner the West Brom striker once again.
"It's a positive move, we're a small nation with limited resources and we need people of his quality," said Bellamy.
