Barcelona playmaker Deco believes Manchester United are strong
contenders to lift this season's Champions League trophy.
The Portuguese international is sure Sir Alex Ferguson's summer
signings have done much to strengthen United's campaign to succeed
in Europe's elite competition.
Deco also admits reigning champions AC Milan are always likely to
be a threat, while he is intrigued to see how Arsenal's youngsters
cope with a testing European campaign.
"United are strong," he told Champions magazine. "They have
improved since last season with their new signings.
"AC Milan are always the same. They seem dead in the water, seem to
be playing badly but in the final stages they become too strong.
And Real Madrid signed pretty wisely in the summer.
"I am curious about Arsenal, to see if they can keep going until
the end of the season. And we have to see what is to be of
Chelsea."
