Iker Muniain has insisted that Athletic Bilbao will travel to Manchester United tomorrow night with a positive attitude.
Spanish club Bilbao will make the trip to Old Trafford as underdogs for the Europa League tie.
However, midfielder Muniain believes that his team are capable of giving the Red Devils "a scare".
"We're going there with every intention of giving Manchester United a scare and getting a positive result for the return leg," said Muniain. "It's a game we've been looking forward to for a long time."
Muniain, 19, made his Bilbao debut in 2009.
