Alex Oxlade-Chamberlain insists his brilliant Celtic debut winner is just the start as he aims to "repay" the club for relaunching his career.
The 32-year-old former England midfielder had gone five months without a club, and was training with former team Arsenal, before being handed a deal by Martin O'Neill until the end of the season.
"This time a couple of weeks ago I didn't know where my future was in the game," Oxlade-Chamberlain said.
"I kept my head down, trained hard and kept believing that something else would come up. Now I'm going to do everything I can to repay the club with the faith they've put in me."
Oxlade-Chamberlain made an immediate and stunning impact for Celtic, coming off the bench to curl in a stoppage-time winner against bottom club Livingston on a dramatic night in the title race.
"It's been the best part of my season so far," the former England international said of his goal.
"I thought the atmosphere was really good, especially after the goal.
"That means a lot and I think it's our job now to be more clinical, put games to bed earlier if we can and play the football the fans want to see and go and win games with authority. That's our job."
And the reaction to his goal on Wednesday night gave Oxlade-Chamberlain an insight into what former Celtic goalkeeper Joe Hart had been telling him about.
"I spoke to Joe Hart about four weeks ago about this place," he added.
"This was before this opportunity had come up. He was just telling me about his time here, how much he loved it and how the stadium can be when things are going well.
"I've just seen a real good glimpse of it."
