Helsingborg coach Age Hareide has told his side they must stop Celtic scoring an away goal in the first leg of their Champions League play-off in Sweden.
The former Norway coach believes Neil Lennon’s men are favourites to win the tie but insists his side have a chance if they keep a clean sheet at home.
In the last round Helsingborg beat Polish side Slask Wroclaw 6-1 on aggregate after a 3-0 away win in the first leg.
Speaking ahead of Tuesday’s match he told Press Association Sport: "The most important thing is not to let Celtic score an away goal.
"That is the key to the tie. If they do score it will be very difficult for us.
"We don't necessarily need to take a lead to Parkhead. We had a good experience in Poland in the second qualifier, we did really well there and we defend well when we stick together.
"Celtic are favourites, they are a big club with good players.
"But expectations are high in Helsingborg with regards to Europe and the fans will be behind us at home.
"We have a good record there, I think we have only lost one game in two years, so we are strong and we played very well in our last home game (a 7-2 win over Kalmar).
"It will be an interesting tie. Tactics are important over two legs and things can change from one game to the other but we have to go into the game in a positive manner."
Former Rangers player Alejandro Bedoya scored on his Helsingborg debut as they went down 2-1 to Elfsborg at the weekend.
But Hareide says that will have no effect on his players against the Scottish champions.
He added: "We played well in the first half and were winning 1-0 but we lost our legs a bit in the second half.
"We were playing on an artificial pitch which wasn't great.
"I also rested players for the game on Tuesday, some of them have played many games already this season.
"We will see who is fit today and get ready for Tuesday. We got the scouting report and we will make plans.
"I have seen Celtic against Helsinki and against Aberdeen and they are a good team, a hard-working side who are well organised and who can play different formations.
"Of course I know Thomas Rogne who is Norwegian and Georgios Samaras played for Greece against Norway when I was national team coach and we will have to watch him."
