Atletico Madrid boss Diego Simeone has told his team they will have to be prepared to suffer "vertigo" during Tuesday's Champions League last-16 second leg at Old Trafford.
The tie is delicately poised after a 1-1 draw in Madrid three weeks ago and Simeone knows his side will have their difficult moments against United in front of a packed Old Trafford. But the Argentine believes Atletico - who have won three successive La Liga games since the first leg - are equipped to hurt United on the break during the game.
The absence of the away goals rule makes any goal for the visitors marginally less concerning for United. As such, Simeone is expecting a classic tie.
