Stuart Armstrong believes Celtic need to go to Iceland this week with the aim of mirroring the 2-0 scoreline from the first leg.

Goals from Dedryck Boyata and Stefan Johansen have given Celtic a solid cushion going into the second leg of their Uefa second qualifying round against the Icelandic champions.

But Armstrong is mindful of the fact the game is simply poised at the half-way mark.

The Hoops will face a trip to either Azerbaijan or Montenegro should they prevail against FC Stjarnan on Wednesday evening.

However, Ronny Deila has banished all talk of the next round until business is taken care of against the Icelandic champions.

“It is a nice 2-0 scoreline but it will still be tricky over there and we know that we really need to do the same again,” Armstrong told Celtic TV..

“We had a lot of possession and they were hard to break down. It was good to get the win and that was important. “It was an important goal for Dedryck, I think he has been terrific for us.

“There wasn’t a panic to get a goal but it was good that we added a second.”

Meanwhile, Leigh Griffiths netted a hat-trick on Saturday evening as Celtic thumped Eibar 4-1 in a game that was arranged to mark the La Liga’s side 75 anniversary.

However, the striker is unsure about whether or not it will earn him a starting jersey against Stjarnan.

“You never know about midweek,’ said Griffiths of his starting chances for ahead of Wednesday night. “I’ll work hard in training and, hopefully, take my chance.

“Nadir has different attributes. He’s a big, strong guy who can hold the ball up well. I like to run in behind defenders and stretch them. I’m hoping we can play together as he’s someone who I can really play off.”

And Hoops skipper Scott Brown, one of the most experienced European performers in the Parkhead dressing room, has warned that it could be a difficult 90 minutes in Iceland this week.

The Hoops should comfortably complete the job they have started but Brown knows that it is vital for Celtic to simply see the game out and make it through the tie.

“It is going to be hard to go away from home but we have that 2-0 lead and we are looking forward to it,” he told Sky Sports.

“Everyone is going to push as far as they possibly can. But we know that if we perform week in, week out as we can then we should be winning this league. That is what we are trying to look forward to. “
