Manchester United and Inter Milan played to a 0-0 tie Tuesday night in the first leg of a European Champions League matchup between the league leaders in England and Italy, extending its unbeaten streak in the competition to a record 20 games.
Cristiano Ronaldo, the FIFA world player of the year, had a great scoring chance in the fifth minute, but his header was saved by Inter goalkeeper Julio Cesar.
Ryan Giggs had an opportunity in the 22nd minute off a cross from Ronaldo, but Inter cleared the ball for a corner kick. United's Dimitar Berbatov was wide with a header off Patrice Evra's cross.
Manchester United hasn't lost in the Champions League since May 2007 against AC Milan. It broke the unbeaten mark it shared with Ajax Amsterdam (September 1994-April 1996) and Bayern Munich (March 2001-April 2002).
"They had a better intensity and speed than us," Inter coach Jose Mourinho said. "Their players played well on the counter-attack, but they didn't score.
"My team controlled them very well. It will be a very difficult second leg."
The second leg of the total-goals, second-round series will be March 11 at Old Trafford.
Manchester United leads the English Premier League by five points over second-place Liverpool, while Inter holds a nine-point margin over second-place Juventus in Italy's Serie A.
"I think that it is obviously a disappointment we haven't won the game, that's for sure," United manager Alex Ferguson said. "In front of our own fans, that's what we must we must do."
In other games, Arsenal beat visiting AS Roma 1-0, Barcelona tied 1-1 at Lyon, and Porto tied 2-2 at Atletico de Madrid.
On Wednesday, Juventus is at Chelsea, Liverpool at Real Madrid, Bayern Munich at Sporting Lisbon and Panathinaikos at Villarreal.
'You have to be ready when the bell rings'
At London, Arsenal's Robin van Persie converted a 37th-minute penalty kick after he was tripped by defender Philippe Mexes.
Arsenal began the second half two men short because defenders Kolo Toure and William Gallas were slow returning from the locker room.
Toure got a yellow card when he tried to get onto the field with the game in progress.
Gallas entered later.
Arsenal manager Arsene Wenger said Toure's habit was to be last out of the changing room and that Gallas was still getting treatment for injuries.
"They did not know that the game had started without them," Wenger said. "It's our fault because you have to be ready when the bell rings to go out."
At Lyon, Juninho scored in the seventh minute, his 42nd goal off a free kick with Lyon, but Thierry Henry tied the score in the 67th minute with a header after Rafael Marquez flicked on Lionel Messi's corner kick.
Barcelona's Samuel Eto'o and Lyon's Karim Benzema each hit a post during the first half.
At Madrid, Lisandro Lopez in the 22nd and 72nd minutes for Porto, giving him six goals in seven European matches.
Atletico got goals from Maxi Rodriguez in the third minute and Diego Forlan in first-half injury time, a shot that slipped in off the hands of goalkeeper Helton.
