Striker Leigh Griffiths is confident Celtic will progress to the Scottish Cup fifth round by beating Stranraer on Sunday.

The Hoops have been in indifferent form in recent weeks as they have only won three of their last eight matches in all competitions, with Saturday’s 1-0 league win over Partick Thistle doing little to ease the concern surrounding Celtic Park.

Ronny Deila’s side will now turn their attention to cup action when they take on Brian Reid’s Stranraer side at Stair Park and Scotland international Griffiths knows nothing short of an emphatic victory will do for the Glasgow giants.

He said: “There is going to be pressure on us to win the game, comfortably as well.”

The 25-year-old admits that the third-tier outfit will make it tough for Celtic to secure their place in the last 16, but he is confident they have what it takes to avoid a potential giant-killing act.

Griffiths added: “We will go down there, Stranraer will make it difficult for us. We have to adapt to conditions and, whatever team goes out, we are confident of getting through.”

The Bhoys have won the two previous meetings between the two sides, with their last visit to Stair Park ending in a 4-1 victory in the same competition back in 2001.

Celtic are overwhelming favourites at 1.14 to win, whilst Stranraer are available at 19.00 and the draw is on offer at 7.50.
