The Celtic hitman missed the second half of last season.

Frank McAvennie is delighted to see Celtic hitman Leigh Griffiths fit and firing again.
Griffiths has been in red-hot form for the Hoops in pre-season so far and scored four against St Gallen Under-21s on Tuesday.
The 28-year-old missed the second half of last season after struggling with a bout of depression.
But it looks like the Celtic hitman is getting back to his best in preparation for the 2019-20 campaign, and Bhoys legend McAvennie has sent him a message on Twitter.
Celtic boss Neil Lennon said last month that getting Griffiths back was the equivalent of having a new £6 million striker available to him.
But an in-form Griffiths is worth more than that. After all, this is a player who scored 40 goals during the 2015-16 campaign. Nobody in Scotland has got even close to that since. The closest Moussa Dembele and Alfredo Morelos came was the 30-goal mark.
The former Hibs forward is in a league of his own when he’s enjoying his football and he’ll be one hell of a competition for Odsonne Edouard this coming season.
