Leigh Griffiths has completed his transfer to Celtic, penning a four-year contract with the Scottish champions.

The striker arrived at the Glasgow side's training ground earlier today to undergo a medical ahead of the move from Wolverhampton Wanderers.

The striker told his new club's website: "I'm over the moon. It's been a long time coming. Ever since I heard Celtic were interested there was only one place I wanted to play and I'm just glad it's done now.

"It was the middle of December and my agent gave me a phone and said Celtic could be interested in January and I have just been counting down the days.

"We are the Scottish champions to begin with, and this is a massive club with a massive fanbase and a massive stadium. I have watched the Champions League nights on the TV and there is no better place to play. This is where I want to be."

Griffiths has scored 12 goals for Wolves in League One this season.
