Mourinho snatches perfect start as big teams dominate

While Real were giving Ajax a harsh lesson on their return to the European elite, Arsenal began their campaign with a ruthless 6-0 victory over Braga and Chelsea saw off Zilina 4-1 in another gross mismatch.

AC Milan and Bayern Munich had far tougher assignments in their opening games and needed their strikers to come to the second-half rescue.

Zlatan Ibrahimovic capped his Milan home debut with a quickfire double that secured a 2-0 win over Auxerre, while Thomas Mueller and Miroslav Klose struck late to give last season's beaten finalists a 2-0 victory over AS Roma.

Inter Milan defeated Bayern in the final at the Bernabeu in May, when Mourinho clinched his second Champions League success and promptly accepted a move to Real Madrid.

His target is to deliver the club's 10th European Cup, and first since 2002, an achievement that would make him the first coach to win the Champions League with three different clubs.

Back in the stadium where he celebrated Inter's success, Mourinho witnessed an outstanding Group G performance against four-times champions Ajax, who endured an unhappy night on their Champions League return after a five-year absence.

Only Real's finishing let them down and Mourinho reacted furiously as the chances came and went before an own-goal from Vurnon Anita settled their nerves and a 73rd-minute volley from Gonzalo Higuain wrapped up the win. 

It can happen that in a match when you play badly you score three goals and other times you can do everything on the pitch but score," said Mourinho who also led Porto to the trophy. "The goals will come."

Real's main Group G rivals are Milan, the seven-times winners who looked to be heading for trouble against Auxerre before Ibrahimovic justified the effusive welcome back to the San Siro he was given by fans.
