Defending Champion MU

A quick look at the teams involved.

ARSENAL

The Gunners have stuttered their way through this season but may be hitting form at just the right time. Arsenal have players of the quality of Theo Walcott, Cesc Fabregas and Eduardo coming back from injury and seem to have struck a better balance in Europe this season. Arsene Wenger will probably want to avoid English opposition and they will need to rediscover their scoring touch if they are to make the last four.

BARCELONA

The Catalan giants are tournament favourites based on their blistering attacking play to date, disposing of Lyon 6-3 in the last round. The attacking triumvirate of Thierry Henry, Samuel Eto'o and Lionel Messi strikes fear into defences across the continent but there are question marks over their defence based on recent stuttering form in La Liga. Barcelona will be confident whoever they face and they have every reason to be.

BAYERN MUNICH

The German aristocrats made people sit up and take notice with their record thrashing of Sporting Lisbon in the last round. They have shown solid form throughout and possess players of real quality in winger Frank Ribery and full-back Philipp Lahm. The Allianz Arena is a difficult place to play but they will want to avoid the English giants if they are to progress.

CHELSEA

Chelsea have undergone a quiet transformation since the arrival of interim manager Guus Hiddink. Without being spectacular they seem to have rediscovered the spirit which made them so difficult to beat in the past. Michael Essien is back after a long injury lay-off to bolster their midfield and if Didier Drogba and Frank Lampard can continue their current form they may have what it takes to deliver that elusive Champions League title to Stamford Bridge.

LIVERPOOL

Liverpool are flying after superb results against Real Madrid and Manchester United, and with manager Rafa Benitez signing a new five-year contract there is a real feel-good factor around the club. Captain Steven Gerrard is bullish about their chances, telling Liverpool FC magazine: "We are not running scared of anybody. We will take who we get and believe that we are going to go through."

MANCHESTER UNITED THE STRONGEST CONTENDER AND DEFENDING CHAMPION

The Premier League and European champions have been imperious this season but a stuttering win against Inter Milan and last weekend's thrashing by Liverpool have given other teams in the draw some hope. Defender Nemanja Vidic believes the Premier League is the strongest in Europe but admits, "whoever we play will be difficult because they are all top teams now." Expect a reaction following the Liverpool result and another place in the semi-final seems more than likely.

PORTO

Undoubtedly the outsiders of the draw and probably the team everyone else would like to meet. The 2004 winners topped Arsenal`s group this season and disposed of an attacking Atletico Madrid side in the last round, so should not be completely discounted. In Lisandro Lopez they have a striker who knows how to score at this level, with six this season to date, but the impression is the quarter-finals will be where their adventure ends.

VILLARREAL

The smaller of the Spanish sides in the draw, the Yellow Submarine showed their tidy brand of football earlier in the competition when drawing twice with champions Manchester United. They possess quality in playmakers Santi Cazorla and Ariel Ibagaza and coach Manuel Pellegrini says his side "are focused on getting as far as possible." Villarreal will be tough opponents but a semi-final berth seems beyond them.
