Real Madrid hammered 10-man Tottenham 4-0 in the first leg of their Champions League quarterfinal on Tuesday.

Adebayor beat Jermaine Jenas to the ball after just four minutes at the Santiago Bernabeu Stadium to guide a header past goalkeeper Heurelho Gomes and through the legs of Luka Modric on the line.

Tottenham was left with 10 men from the 15th minute when Peter Crouch earned a second booking for a rash tackle.

Nine-time champion Madrid has never been eliminated over two legs after a 4-0 opening win on home soil.

''It's going to be very difficult - we have a mountain to climb'' Redknapp said, adding that the difference in quality had much to do with Madrid's spending. ''It's difficult, impossible to compete with teams like that.''
