Fury coach Ian Ferguson said the young midfielder had proven himself over the past three weeks at the club and had impressed in his appearance in the club's Singapore tour match against Tampines Rovers.

"Osama fits in well - he doesn't look out of place at all," Ferguson said. "He did very well on the trip and he fills one of those under-21 spots I was looking for. He's a young player who I think can come on and play A-League and do well."

Ferguson admitted there was a moment during the trial period when he wasn't sure Malik was what he was looking for, but praised the talented youngster for working his way back into form.

"I like to give the boys a bit of time rather than make a decision in a couple of days and Osama is one of those players who came in strong and then went into a bit of a hole, but showed great character to pull himself out of it with his work ethic and consistency at training," Ferguson said. "He's a stand-out kid with a lot of great qualities."

Malik said the move from Adelaide, where he played in the National Youth League and was called up to the first team squad during the Club World Cup, was exciting.

"It's been a really enjoyable three weeks and there's a really strong relationship between the staff and the players which makes it a bit easier," Malik said.

"The Gaffer is great - training is really enjoyable and with a record like his, there's a respect there, but he also has a laugh with the boys and it's a really good environment."

North Queensland Fury are now focussed on filling the two remaining under -21 spots and will have Razorback forward Ramone Close onboard for this weekend's trip to Rockhampton where Fury will play the Capricorn Cougars and Central Coast Mariners in Rockhampton.
