Roar seals deal for Do

The 19-year-old left-sided attacker impressed Roar during a trial period in May and becomes the club's latest foreign player.

"He's a very exciting young player," Brisbane Roar coach Rado Vidosic said.

"We felt that we needed another left-footed player with a more direct style of play to compliment what we already have got.

"Now, we've got more combinations we can apply and I'm very excited about that."

Vidosic said the injection of Do would ensure a more central midfield role for Broich, who claimed the A-League's best player award last season.

"... it definitely gets him more involved because in the middle you get more touches," Vidosic said of Broich.

"With the speed that we have got now out wide we can really penetrate and be even more dangerous."

Vidosic licked his lips at the prospect of Do linking with the likes of fellow attacking weapons Broich, Besart Berisha and fellow new boy Ben Halloran.

"With the attacking brand and aggressive defence that we have used the last two years I am quite sure that we will again be one of the front runners," he said.

"If we can get all the small details right I am sure we will be very hard to defeat."

The two-time defending champion Roar has one visa spot remaining after Bahrain international defender Mohamed Adnan knocked back the chance to re-sign with the club, returning instead to the Gulf region for family reasons.

Roar coach Rado Vidosic has previously said he will look abroad for a replacement with Do the club's 20th contracted player.
