Aloisi wants to 'lock down' Borrello

Brisbane Roar coach John Aloisi has reiterated his desire to 'lock down' attacker Brandon Borrello amid a stand-off with his management over a new contract.

Borrello was surprisingly left out of Brisbane's side for the 2-1 win over Wellington Phoenix in Cairns at the weekend, but has been included in an extended squad for Sunday's away clash with the Central Coast Mariners.

The 20-year-old remains tied to Roar only on a full-time youth deal which expires at the end of the season, leaving him as one of 12 out-of-contract players currently free to talk with other clubs.

Negotiations over an upgraded deal have stalled, with Borrello and his agent John Grimaud happy to keep their options open amid nibbles of interest from overseas and recent uncertainty regarding his position in the pecking order in a jam-packed Roar team.

"We want to lock Brandon down, I said it from the first two days I joined the club that I want Brandon to stay," Aloisi said.

"I think he's a big part of our future - in the immediate future, the next couple of years - and then hopefully one day he can go overseas and fulfill his potential.

"At the moment, that doesn't change. We want Brandon to stay."

Borrello hasn't scored since accepting the October nomination for the A-League's young player of the year award.

Having started in each of Brisbane's first eight matches of the season, the Adelaide-born forward was dropped to the bench for the 2-1 loss to Western Sydney Wanderers, didn't feature against Phoenix and is seemingly out of favour.

"Brandon hasn't put his head down, he's been working hard in training," Aloisi said.
