Griffiths wants more minutes at Wolves
Griffiths is also dreaming of tackling the likes of Chelsea.
He told the Scottish Sun: "I have a Chelsea strip which my brother Paul got me, although I'm not sure why I started liking them.
"It is a massive step up to come to the Premier League.
"I have gone from training at Caird Park in Dundee to our own training ground at Wolves. They have undersoil heating on their training parks. It is night and day."
