Arsenal out to overturn deficit

LONDON: Sol Campbell expects Arsenal to use the painful memories of their farcical Champions League first round defeat in Porto to kill off the Portuguese champions in the decisive second leg on Tuesday.

Arsene Wenger's side must overcome a 2-1 deficit at the Emirates Stadium following a self-inflicted first leg loss that featured two bizarre mistakes by goalkeeper Lukasz Fabianski.

Reaching the last eight should be more than enough incentive for Arsenal but former England defender Campbell, 35, believes the manner of the first leg defeat could provide an important additional motivation. Gunners boss Arsene Wenger was less than impressed by the way Swedish official Martin Hansson allowed the free-kick to be taken so quickly and Campbell agrees that Arsenal were hard done by.

While Porto's European progress would be guaranteed with a draw, midfielder Raul Meireles insists there is no chance of the visitors playing cautiously at the Emirates. Porto need success in the Champions League to keep their season alive as they sit eight points behind Portuguese leaders Braga.

"We will not be ultra-defensive in London. That's not our style and to try to play that way would be a disaster for us," Meireles said. "Arsenal are a dangerous team in attack and to give them the ball would cause chaos for us. I'm optimistic and our squad have the confidence and belief that we will reach the last eight."

Bayern favourite to advance

ROME: There cannot be two sides in the last 16 of the Champions League whose recent form has been more contrasting than Fiorentina and Bayern Munich.

They come together for the second leg in Italy on Tuesday with Bayern not only up 2-1 from the opening leg but in rude health having usurped Bayer Leverkusen from top spot in the Bundesliga. Despite conceding an early goal from former striker Lukas Podolski, Bayern fought back to equalise 1-1 against Cologne on Saturday, extending their five-month unbeaten run in the league to 18 games.

Fiorentina, meanwhile, have been in freefall since around the time Adrian Mutu tested positive for a banned substance in late January. After an impressive opening to their Serie A campaign and particularly in the Champions League group stage where they did the double over Liverpool, the Viola have registered just one win in nine matches. While Fiorentina are looking to break new ground, Bayern have been crowned champions of Europe four times -- 1974, 1975, 1976 and 2001. Louis van Gaal has fashioned competitive Bayern side after recovering from a stuttering start to his reign.
