Striker Ryan Griffiths says Adelaide United's attractive game style is what lured him to the side.

Marksman Ryan Griffiths says Adelaide United's attractive brand of soccer has lured him to the A-League club in an unexpected deal.

Griffiths was training with his former A-League club Newcastle Jets on Monday, eyeing a return to Asia next season, when Adelaide pitched him an offer.

"I was actually looking at places in Asia and I got the phone call (from Adelaide) and it was a great offer," Griffiths told reporters on Thursday.

"Adelaide seemed really keen to get me on board so that was one major factor.

"But another factor is they play a really nice brand of football and something that I feel I can just come straight into."

Adelaide, in the wake of injuries to striker Bruce Djite (groin) and attacking midfielders Cirio (hamstring) and Marcelo Carrusca (knee), were keen to add some forward firepower.

Griffiths, who hasn't played for two months since a stint with China's Beijing Baxy, rejected overtures from other A-League clubs to join the Reds.

Adelaide coach Josep Gombau wants to play the 32-year-old in Saturday's away match against league leaders Brisbane.

"There are a lot of injuries at the moment so I think Josep wants to put me straight in. But, in all honesty, I'm not sure where I am at in terms of match fitness," Griffiths said.

"I haven't played for two months. It would be nice to ease my way in, but it might not be that way.

"My conditioning is not too bad but, when I go into a game at full speed, it's completely different. And Brisbane Roar being a team that they are, really fast and furious, it's going to be tough."
