As the UEFA Champions League group stage reaches its end, both Chelsea and Porto are yet to guarantee their spot in the next phase of the competition.
The Blues' second half of the group stage has proven more successful than the first, with the decisive match set to be played at Stamford Bridge. The hosts need just a point to secure a spot in the last 16.
A draw, however, is not enough for Porto. The Portuguese side are second in Group G, level on points with leaders Chelsea, and need to win in west London if they're to qualify without relying on the result from Dynamo Kiev vs Maccabi Tel Aviv.

If all three teams end the group stage with eleven points, Porto face elimation given their inferior head-to-head goal difference.
It's been a turbulent season for both clubs thus far. Chelsea lost the Community Shield back in August to Arsenal and were knocked out of the Capital One Cup after a penalty shootout against Stoke.
The west Londoners are yet to show form worthy of defending champions in the Premier League and find themselves 14th on 15 points, 17 behind first-place Leicester City.
However, it appears Mourinho still has Chelsea fans on his side and, given their final game will be played in front of the Stamford Bridge faithful, sit in the most comfortable position to finish top of Group G.
For Porto, the story is different. The Portuguese outfit sit second in the Primeira Liga, two points shy of leaders Sporting Lisbon. However, recent performances have brought manager Julen Lopetegui’s position into question.
After a season of record-breaking investment yet no trophies to show, early elimination from the Champions League would be heavily criticised by those associated with the club.
Both Mourinho and Lopetegui will hope for qualification when the two face off on Wednesday night, not just for their clubs' season ambitions, but also for their respective futures.
