ADELAIDE United is waiting for an answer from a potential star marquee signing.

United’s general manager of football Ante Kovacevic, says the club will in the next 48 hours find out if it has secured the international striker who played for his country in the qualification stage of the 2006 FIFA World Cup. The striker has played for years in Germany’s Bundesliga, is in his thirties and will become Adelaide’s most significant signing in the history of the club — if the Reds can pull it off.

Kovacevic would not name the striker who is now considering the marquee offer but revealed he is not Spanish.

“We have submitted an offer and now we’re waiting to see which way it will go in the next couple of days,’’ Kovacevic said.

“This striker has been at the top of his game for years and I feel it will be the club’s most significant signing. He is a proven goalscorer.”

FFA is also keen to see the forward become part of the A-League.

Kovacevic also revealed the club was close to signing an experienced Australian winger to bolster its squad this week.

But he claimed a centre back — given Nikolai Topor-Stanley had been presented to the club as an option from Western Sydney — wasn’t a top priority for the new season.

With Adelaide officially announcing it had signed youth team players Jordan O’Doherty, 18, and Riley McGree, 17, to one-year contracts on Monday, the Reds’ main objective was to secure a striker and winger while attacking midfielders — one to replace Stefan Mauk (NEC) in particular — are further down the list of must-haves.

Adelaide will face Melbourne City in a friendly behind closed doors in Melbourne Wednesday as it continues to ramp up its pre-season, which took an embarrassing turn when the Reds were eliminated by Redlands United 2-1 in extra time in the FFA Cup a fortnight ago.

Tim Cahill — City’s high-profile guest player — who trained for the first time with his new club on Monday, is unlikely to play against United.

Bruce Kamau, who scored for the Reds in the grand final, is set to face his former teammates for the first time since leaving the club in May.
