The UEFA Champions League resumes this week with a quartet of ties that look fascinatingly poised as some of Europe's biggest names chase a quarter-final spot.

Former winners Porto and Real Madrid have already booked their spots in the quarter-finals, but Bayern Munich and Chelsea still have plenty to do if they hope to reach the last eight. As for holders Real Madrid, their ten-game winning streak in the Champions League came to an end on Tuesday when they lost 4-3 at home to Schalke. Carlo Ancelotti's side will be short on confidence after their lacklustre performance despite advancing to the last eight.

The history books favour the heavyweights, with previous results in the competition suggesting both Bayern and Chelsea ought to prevail. Chelsea go into their game with a 74.6 per cent chance of progressing – after drawing 1-1 at Paris Saint-Germain – while Bayern's 0-0 stalemate at Shakhtar Donetsk has left them with a 66.3 per cent probability of going through.

Match of the day
Chelsea-Paris Saint-Germain, Stamford Bridge, London, 20.45 CET
Having clawed back a two-goal deficit at home to PSG in last season's quarter-finals, Chelsea enjoy the luxury of letting their French opponents take all the risks this time around. Comfortably clear in the Premier League, the Blues are aiming for a fourth last-eight berth in five years and their seventh in the last nine campaigns, and they also go into the game fresh from a weekend off. Paris had to tackle Lens, in contrast, but Laurent Blanc's men raised spirits with a commanding 4-1 victory. "We'll need to score away against Chelsea," said the Paris coach. "I hope we'll be more clinical and that we'll have a higher ratio of goals to chances than we did today." Blanc will thus be delighted that he can call on a full squad, with Thiago Motta a notable option again after injury. The midfielder's return should mean former Chelsea player David Luiz dropping back into defence, though not before he has given Blanc a full briefing on how Chelsea approached the decider against PSG last season.

Elsewhere
Shakhtar Donetsk managed to frustrate Bayern in the opening leg, showing once again that they can rival even the very best on home soil. However, the Ukrainian contenders are a less menacing proposition on their travels, and have not scored away against a German club in their last four visits.

PSG talisman Zlatan Ibrahimovic has yet to find the net in seven games against sides coached by Jose Mourinho. The Sweden captain fared much better under the Portuguese coach, on the other hand, mustering 28 goals in 46 outings for Mourinho's Inter Milan.

Bayern, Atletico Madrid and Monaco are the only teams to have kept clean sheets in all of their Champions League home matches so far this season.
