Europe's finest going for goals

'Porto hearts'
The spectre of José Mourinho adds much of the spice to the occasion, the fixture coming four months after he masterminded Porto's triumph in this competition. Despite such achievements, the Chelsea manager is unsure as to the reception he will receive from the visiting fans at Stamford Bridge. "If they are pure supporters who have always had Porto hearts, they cannot forget what I did with the club," he said.

Unbeaten Arsenal
Mourinho has wasted little time in making his mark in London, guiding Chelsea to an opening 3-0 victory at Paris Saint-Germain FC while Porto were being held by PFC CSKA Moskva. The Parisians are in Moscow for today's early kick-off. Like Chelsea, Arsenal FC are unbeaten in the Premiership and won their European opener, 1-0 at home to PSV Eindhoven.

First meeting
Maximum points will be similarly hard to come by at the Champions League's most northerly city, Trondheim. "No one gets a walkover at Lerkendal," said Rosenborg BK coach Ola By Rise, whose side need to bounce back having lost 2-1 at Panathinaikos FC a fortnight ago. The Greek champions are at PSV for the first meeting of these clubs.

Ronaldinho 'can't wait'
There is a strong Ukrainian presence in Group F, as the country's league leaders, FC Shakhtar Donetsk, travel to FC Barcelona and the country's premier player, Andriy Shevchenko, leads the line for AC Milan against Celtic FC. Shakhtar will do well to replicate their domestic form at Camp Nou, particularly as Ronaldinho "can't wait" to make his home Champions League debut. "I'm going to love seeing the stadium full and noisy," he said.

Away record
Ronaldinho impressed as Barça beat Celtic 3-1, giving them early breathing space in Group F along with Shakhtar's conquerors Milan. Milan play Celtic tonight, 35 years on from their defeat of the Scottish team en route to European Champion Clubs' Cup glory. Celtic have lost all six of their away matches in this competition, while Milan's city rivals FC Internazionale Milano have a similarly indifferent recent record.

'In the mood'
The Nerazzurri are winless in six Champions League away games ahead of their tie at RSC Anderlecht, whose coach, Hugo Broos, is expecting a telling performance from his players. "They've been looking good in training and really look in the mood to produce something special on Wednesday night." The other Group G fixture sees the champions of Germany and Spain meet at the Weserstadion as Werder Bremen tackle Valencia CF.
