In a big week for the Reds keepers, reserve stopper Mark Birighitti has also signed on for another two seasons.

Galekovic has been a fantastic acquisition for the Reds after joining from Melbourne Victory in October 2007. He was voted club champion in just his second season and is regarded as one of the best stoppers in the competition.

The Reds have managed to convince the 28-year-old to stay rather than return to Melbourne to play for the new franchise which is set to make its debut next season.

"Obviously a four year deal gives me a bit of security and lets Adelaide United know where they stand as well, so I'm happy to sign a long term deal and I think Adelaide United are to," Galekovic said.

"Adelaide was my first preference, obviously there were a lot of plus sides to go back to Melbourne but in the end, Adelaide has treated me well and I'd like to pretty much finish my career up in Adelaide if I don't go overseas."

Galekovic said the only reason he would leave the club would be to take up an offer from a European club.

"It is not something I'm pushing to do but if offers do come from overseas, any player would have to look at it. But in saying that, if I'm going to play in Australia, I want to finish my career off in Adelaide, because it has been a great club, and a great club to me, so I'd just like to repay that faith to them," Galekovic said.

"When you're playing regular football you start enjoying your football more, and I'm pretty much at my peak as a goalkeeper, so I'm happy to give my best to Adelaide United while I'm at my peak."

Galekovic's understudy, 18-year-old Birighitti, is happy to continue his development under the No.1 stopper.

"I'm really happy to have signed for two more years. It's a great club, the boys have great to me and I have a good relationship with the coaches and the boys, so it would be hard to go to another club even though I was coming out of contract," Birighitti said.

Like Galekovic he also harbours ambitions of European football, but is happy to stay put for the time being.

"Deep down I knew I wasn't ready yet to make that big move overseas, so a few good seasons in the A-League playing regularly in the first team will do me good, and then I can make the move overseas when I know I'm ready and the time is right," Birighitti said.

Birighitti has made two Hyundai A-League appearances to date.
