Celtic striker Leigh Griffiths signs new deal until 2021
Leigh Griffiths believes he can realise his Champions League ambitions at Celtic after signing an extended deal that ties him to the club until 2021.
Griffiths says he is happy to stay with the Scottish champions, who he believes are a bigger club than "three quarters" of the English Premier League.
"I want to win a lot of trophies, but most importantly I want to play in the Champions League," he said.
"I don't see why I really need to leave this club."
With Celtic falling at the Champions League qualifying stages for the past two seasons, Griffiths has yet to sample Europe's premier club competition, but the 25-year-old is confident he will do that with the Glasgow side.
"I've been there at a couple of Champions League nights here - I don't think there's a better atmosphere in European football and I want to sample that for myself," he said.
"That's the main aim, especially for the boys that haven't played there before.
