Real Madrid manager Jose Mourinho says "the world will stop to watch" Tuesday's Champions League last-16 match at Manchester United.
.
The tie is well poised after the two sides drew 1-1 in the first leg at the Bernabeu.
.
And Real coach Mourinho believes the game will live up to all the expectations of it.
.
"The world will stop to watch this tie. I doubt expectations can be bigger than for this one," he said.
.
The last time Manchester United hosted Real Madrid at Old Trafford was in April 2003 in what is widely considered one of the greatest matches in European club competition.
.
Manchester United won 4-3 on the night but a hat- trick by Brazilian Ronaldo ensured Real progressed 6-5 on aggregate.
.
"Nobody knows what will happen because the teams are well matched." Real arrive at Old Trafford after two "El Clasico" wins over Barcelona.
.
They first saw off their Spanish rivals 3-1 in the semi- finals of the Copa del Rey on 26 February, before beating them 2-1 in La Liga on Saturday. "Our feelings would be the same whatever those results," added Mourinho. "The first match against Barcelona put us in the cup final, the second was in a league - a league we cannot win - and this is the Champions League.
.
"They are independent competitions with independent feelings but of course it is better to come here in a period when the players are happy and the players have beaten a rival twice. The moment is fine."
.
However, United also head into Tuesday's encounter in excellent form.
