Celtic goalkeeper Fraser Forster has insisted that the "job is only half done" ahead of the club's Champions League qualifier second leg against Elfsborg.
The Hoops travel to the Swedish champions on Wednesday with a narrow 1-0 lead from last week's match at Parkhead.
"It will be a tough game, no doubt about it – you aren't champions of your own country without being a very good team," Forster told the club's official website. "We had a good result last week but know the job is only half done."
Celtic famously reached the last 16 of last season's competition before being knocked out by Juventus.
