Young Boys coach Gerry Seoane insists they go into their Champions League clash with Manchester United capable of an upset.

Seoane knows United boss Jose Mourinho has never won on Swiss soil.

"We will do everything so it will continue," replied Seoane. "But we know that a big club with a great coach is playing against us. They have shaped football at the highest level in recent years."

For many, this is the biggest game in YBB's history.

Seoane added: "It should not go into the positive or the negative. At the moment I have no big emotions.

"Everything is possible in every game. Everything is possible if you bring the appropriate performance."
