Video: Gareth Bale expects tough Borussia Dortmund test

Gareth Bale has revealed that he expects a difficult match when Real Madrid travel to Borussia Dortmund on Tuesday for the second leg of their Champions League quarter-final.

Madrid are in control of the tie as it stands thanks to a 3-0 first-leg triumph in the Spanish capital last week.

However, Bale has warned his teammates that they will have to remain focused in Germany if they want to reach the semi-finals of the competition.

Watch the Welshman's exclusive interview with bwin below as he talks about the upcoming match as well as his experiences so far at the Santiago Bernabeu.

Bale has scored 19 goals in 32 appearances for Madrid following his reported £85m move from Tottenham Hotspur last summer.
