Bolton Wanderers defender Andy O'Brien insists they can shock Sporting Lisbon in tonight's UEFA Cup return-leg clash.

Sporting have the edge courtesy of their 1-1 draw at the Reebok last week, but O'Brien says: "The game is going to be a good one because we need to score to get that away goal and make a game of it.

"I'm sure they were happy with the result and the away goal, in particular after they went 1-0 down.

"Their players are very good technically and they will be a good team at home, but we don't fear them.

"We can at least take the positives out of what has so far been a great European adventure."
