Uefa Cup - First qualifying round, second leg
Venue: Racecourse Ground, Wrexham
Date/time: Thurs, 28 July, 1930 BST
TNS manager Ken McKenna insists his side can overturn a two goal deficit and avoid a European exit at the first hurdle for the sixth successive time.
"Conceding a second goal in Sweden has made it a lot harder as we've basically got to score three times to win the tie," said McKenna.
"They're a well organised side, but the job is not beyond us, particularly if we can get an early goal."
Defenders Steve Evans (jaw) and Martyn Naylor (ankle) both still sidelined.
And with left-back Chris King only recently back in training following a hamstring
problem, boss McKenna admits his resources are stretched once again.
TNS operated with Jamie Wood as a lone striker in the first leg a fortnight ago, but the Welsh Premier's only professional side will need to show more attacking intentions at Wrexham's Racecourse Ground on Thursday.
McKenna added: "We'll sit down and decide on how best to approach the game.
"We need to be bolder but at the same time it's a balancing act as we can't afford to concede a goal."
Östers, despite a 3-1 win over IF Brommapojkama in the Swedish Second Division last weekend, have their goalkeeping problems with Peter Kennfors sidelined with a broken hand.
With first-choice Bjorn Stringheim already ruled out, the Swedes have turned to their former stopper Claes Green, now with lower league side Vaxjo BK.
