Brisbane Roar's outstanding start to the A-League season has earned global admirers, with Germany’s Borussia Monchengladbach signing their striker Kwame Yeboah.

The 19-year-old has flown to Germany for a medical with the five-time Bundesliga winners and will miss Friday night's clash with Newcastle before returning for a farewell appearance against Sydney FC on Boxing Day.

Rather than seeing the signing as a hit to Mike Mulvey's young squad, the Roar's football director, Ken Stead, said it was a great achievement for both player and club.

"We will not stand in the way of opportunities like this for our young players," he said.

Announcing the move on Thursday morning, Mulvey said the "substantial offer" was too good to refuse for Yeboah and the club was already working on a replacement.

Five points clear on the top of the league, Mulvey was bullish on his team's prospects for the long run-in. "I've felt it all along that we will be much better, be stronger and play better football in the second half of the season," he said.

With Central Coast, Western Sydney Wanderers and potentially Melbourne Victory all devoting time to their Asian Champions League campaigns, Mulvey spoke of the Roar's competitive advantage.

"They've got Saturday-Wednesday-Saturday [games] for six weeks ... that's very, very difficult. If we really dig deep now and make sure we've got points in the bag, it's going to count for a lot at the end of the season."

The Jets have a good record at Suncorp Stadium, with just one defeat in their past five trips, and gave the Roar one of their only losses this season last time out.

Adam Taggart fired the Jets to a 2-1 win in the wet but Gary van Egmond will hope to have Nathan Burns available again after he missed in their loss to the Wanderers last weekend.
