GELSENKIRCHEN (GERMANY) (Agencies) - Two weeks after knocking out title holder Inter Milan, an unheralded Schalke side is looking to cause another major upset in the Champions League when it plays Manchester United in the first leg of the semi-finals today (Tuesday). Schalke considers itself a total underdog against the three-time champion. But the Bundesliga team was also the outsider against Inter and still went through 7-3 on aggregate. "Of the two teams, we have much less to lose," Schalke coach Ralf Rangnick said Monday. "We may be less experienced, but we are hungry and we have a lot of passion." "Manchester United is a household name, just like Inter Milan before," Schalke midfielder Alexander Baumjohann said. "It's a dream of every player to be facing the Reds in a Champions League semi-final. "Looking at the names, there is hardly any difference between Inter and Man U. The important thing is not to concede at home. Perhaps we can land another upset." Rangnick said he expected a close game. Schalke has won all its home games in the competition, while United has not conceded a goal in four wins and one draw away. Both teams rested some of their top players over the weekend. United still win, 1-0 over Everton, but Schalke lost 1-0 at home to Kaiserslautern. While United is closing in on the Premier League title, Schalke has nothing to play for in the Bundesliga, where it is stuck in the middle of the table. Schalke has managed to reach the semi-finals despite a turbulent few weeks which included the sacking of coach Felix Magath, who was replaced by Rangnick. Influential defender Benedikt Hoewedes missed the game through injury and is in a race against time to avoid joining Dutch striker.
