Athletic Bilbao goalkeeper Unai Simon says tomorrow's clash against Osasuna is a must-win.

Sitting in seventh place, Athletic cannot afford a slip as they target European football.

Simon said, "We need to play with confidence and bravery. We can't play on the back foot and with fear.

"It's the perfect chance to prove we want to get into Europe and we have to take that step. If we play as well as we have done in many of our games this season, maintain our defensive solidity and get it right in the box, we can win.

Simon added: "We got an important win against Celta, but it's not worth anything if we don't beat Osasuna. All that matters is being in the same position the end of the season and Thursday's game is vital if we're to achieve that and get into Europe.

"It makes no difference if you look at the standings. All we have to do is win in Pamplona. There are many teams in the fight and if you don't get points, the rest will catch up. It's in our hands and we have to win

"The older players tell us what it's like to play in Europe, but the youngsters are less aware of what it brings to the Club. "We have to recognise how crucial it is so we can achieve it."
