Thierry Henry has told Arsenal the one thing they must do if they are to upset the odds and beat Real Madrid in the Champions League.
The two clubs will meet for the first time in 18 years in the quarter-finals of this year's competition after Madrid's dramatic victory over Atletico Madrid on Wednesday night.
Los Blancos showcased their inevitability factor in Europe once again as they edged through in a controversial penalty shootout to set up a showdown with the Gunners, who eased past PSV.
If anyone knows what it takes for Arsenal to beat Real Madrid in the Champions League it's Henry, who scored the only goal of last-16 tie when the two sides clashed in 2006.
