Sydney FC striker Alex Brosque intends to slip straight back into his hot run of A-League form when he makes his comeback from a groin injury against Newcastle on Sunday.Brosque has missed Sydney's last two matches after he was injured in the eve of the Socceroos' Asian Cup qualifier with Kuwait earlier this month.In his absence, Sydney have failed to score a goal and surrendered top spot with last week's 1-0 loss to Gold Coast at the Sydney Football Stadium.Sydney FC coach Vitezslav Lavicka confirmed on Friday Brosque had been cleared to make his return and the speedy striker said he hoped to quickly resume the career-best form he displayed prior to his injury."I've been pretty happy with how things have gone this season, so hopefully (getting back to form will take) no time at all," Brosque said."I'm not sure how the team's going to line up this week, but if I can play a part, and I'm hoping I can, then really there's no time to waste."I need to get straight back into going 100 per cent and hopefully I can get back to playing the way I was before I got injured."Brosque said he was almost ready to face the Gold Coast last week but had benefitted from an extra week's rest."I've got no pain or anything like that. Leading into the end of last week I was already feeling quite good, but gave it an extra game just to not aggravate it or anything and start fresh this week," Brosque said."It's always hard to watch from the sidelines, especially last week (the loss to Gold Coast)."It was a frustrating loss, but I think all the boys will put their hand up and say we probably didn't give 100 per cent and it's good we get a chance to turn it around against Newcastle."Brosque said the Sydney players had spoken about the last time they played the Jets, when they suffered a shock 3-1 loss at home and were determined to turn things around at EnergyAustralia Stadium."It was a good wakeup call," he said of the defeat in November."They have run into some very good form and we need to be 100 per cent on our game and bounce back well from last week if we are going to get the points."
