Alex Oxlade-Chamberlain has made an immediate impact at Celtic, scoring a last-minute winner on his debut to secure a 2-1 William Hill Premiership victory over Livingston and keep their title hopes alive.
Earlier this week it was confirmed that Oxlade-Chamberlain had joined Celtic as a free agent after being released by Besiktas earlier this season.
The former Arsenal midfielder had been training at Arsenal to maintain his fitness before agreeing a move north of the border.
Celtic took the lead after 15 minutes when Arne Engels’ corner was cleared to the edge of the area and Marcelo Saracchi smashed home his first goal for the club.
Livingston drew level after Reo Hatate brought down Robbie Muirhead in the box and the striker converted the penalty.
The visitors looked set to claim a point, but in the second minute of added time Oxlade-Chamberlain curled an effort into the far corner to seal the win. He had been brought on as a 78th minute sub to much fanfare from the Celtic fans.
The result moves Celtic to within six points of leaders Hearts, with a game in hand.
The Ox, now 32, has signed a deal until the end of the season with an option for a further year.
