Bulgarian midfielder Radostin Kishishev, 36, believes his home team will cause an upset against England tonight.
The Albion playmaker has racked up 88 appearances for his national side, spanning over a decade, and although disappointed not to be involved tonight, he is backing his team-mates to produce at Wembley.
He told seagulls.co.uk, "England are the strong favourites and this is a huge game for Bulgaria, but I believe England will be frustrated by the way that we play. There may be an upset, believe me.
"Fabio Capello is under tremendous pressure, and in my experience England under-perform against teams from Eastern Europe, especially from countries like Macedonia, Bulgaria, Romania and Slovenia for example.
"It's very difficult for England to cope with our style of play because we keep the ball very well, and we have been known to cheat a bit as well, which is normal for that part of the world. We will make it difficult for England.
"I'm disappointed not to be involved because I still believe that I can do a job for Bulgaria, but at the same time I'm 36-years-old now so I need to give a chance to the younger players to do well.
"I spoke with the manager a few weeks ago, and he asked me to send DVDs so he could watch me play, but unfortunately I am not involved. I can't be upset though because I have played so many games for my country and I have done my job for the national team."
Although not involved in the Euro 2012 qualifier tonight, Kishishev still has ambitions to play in the new Wembley Stadium.
"Wembley is all about the name," he added. "When you hear the word 'Wembley' you know it's something amazing and a place where everyone wants to play because it's so famous all over the world, so I am no different.
"I have been lucky enough to play twice at the old Wembley but have never had the chance to play at the new one. Hopefully one day that will happen."
Meanwhile, the former Premier League midfielder hopes to develop some of the younger players in the Albion squad throughout his one-year contract at the club.
"Part of my role here is to help the younger players become better players. When I was young I learnt from the experienced players by noticing what they did better than the other players. Everyone has their assets and I tried to adopt the best from everyone.
"Hopefully the young players can take bits of me to improve. I'm not saying I'm a great player, but surely from my career I must have something the players can pick up from me to help with their game."
