Return leg: TueReal Madrid   vs   Dortmund    20:45WednesdayBarcelona     vs  Bayern  20:45DORTMUND – Real Madrid coach Jose Mourinho has insisted his side can still reach the Champions League final, despite being routed 4-1 at Borussia Dortmund in the semi-final, first-leg.Poland striker Robert Lewandowski netted all four of Dortmund’s goals to strengthen the possibility of an all-German final at Wembley on May 25, but Cristiano Ronaldo’s away goal gives Real a slim second-leg life line.After Bayern Munich’s 4-0 hammering of Barcelona on Tuesday in the other semi-final, Borussia followed the German champions’ example and floored their Spanish opponents at Dortmund’s Signal Iduna Park.Mourinho’s team now face an uphill battle at the Estadio Santiago Bernabeu in Tuesday’s return leg, but with Real chasing a tenth European title, the 50-year-old self-styled ‘Special One’ has promised they will put up a fight."I have learnt that anything can happen in football, it will be tough next week, but nothing is impossible and my footballers will try to show that next Tuesday,” said Mourinho."The best team by far won.  "Individually and collectively Dortmund were better and deserved their victory. Real only narrowly avoided suffering their worst defeat in international competition - AC Milan beating them 5-0 in what was then the European Cup in the 1988/89 campaign - but Dortmund coach Jurgen Klopp advocated caution."We have to force ourselves to stay focused, we still need to go to Madrid, which will be no walk in the park,” said Klopp."We scored some great goals and played really well, but we have to go to Fortuna Duesseldorf, in the Bundesliga, then Madrid for the second game and there is still a lot to do.”Klopp quickly poured water on any notion his side are now favourites to win the Champions League for the second time in their history after their 1997 triumph."I don’t have the feeling we’re favourites, we produced an exceptional game against a fantastic team, there could have been worse results and we’d still have to go there, we just want to reach the final,” said Klopp.
