Athletic great Andoni Goikoetxea has backed his former club to be in next months final in Bucharest

The Basque club, coached by the eccentric Marcelo Bielsa, are aiming for a meeting on May 9 against Atletico Madrid or Valencia, who start the other semi-final at the Calderon on Thursday.
Goikoetxea was part of the Bilbao side knocked out of the old UEFA Cup by Sporting 27 years ago, the only previous meeting between the sides.
"It will be tough but I'm optimistic because I think Bilbao are a better team, and for this reason I'm convinced they will play the final," the former Spain international told sports daily Marca.
"This team has the chance to make history. They already have a King's Cup final (against Barcelona next month) and we'll see what happens in the Europa League."
Bilbao have never won a European trophy but have thrilled neutral fans with a 5-3 aggregate victory over Manchester United and a 6-4 roller-coaster win over Schalke 04 in the quarter-finals.
The club, who only field Basque-born players, have been praised for their dynamic, attack-minded approach, particularly on the road where they scored three times at Old Trafford and four in Gelsenkirchen. They start their semi in Lisbon.
"Bilbao have a clearly defined style and they never go out to defend," Goikoetxea added. "They are very quick, and are very strong down the flanks.
"Their best games have been against the big clubs, especially against Manchester United, and for that reason they have won European-wide recognition."
