Chelsea have won four of their last six matches against Porto, dating back to 2004.
However, the Blues will have their work cut out for them this week.
After trouncing Maccabi Tel-Aviv two weeks ago en route to an easy three points in Group G, Chelsea now face the hardest match on their schedule with a visit to the reigning Primeira Liga champs in Portugal on Tuesday night.
Jose Mourinho’s men go into the match as marginal underdogs.

While Porto may not inspire fear in fans the way Barcelona, Bayern Munich or PSG do, the Portuguese giants are no slouches and might even be better this year than last year – following the addition of legendary Real Madrid stopper Iker Casillas.
Casillas is not Porto’s only star. Check out five players who Chelsea must be aware of as they travel to Estadio do Dragao…
The veteran Porto defender is a mainstay at centre-back when he’s healthy.
In six seasons since joining the Primeira Liga giants, Maicon has made 108 appearances and contributed 11 goals to go along with his 10 trophies with the club.
He’s a tall, combative and fiery character who won’t be intimidated by Diego Costa.
4. Yacine Brahimi
A tough-as-nails winger coming off a 13-goal campaign, Brahimi is reportedly attracting major looks from Chelsea, who are considering a January transfer bid for him according to the Metro.
Brahimi is a fitness doubt for Tuesday’s match. Chelsea will be hoping he misses out, because he is capable of this sort of wizardly, which is the last thing Branislav Ivanovic needs when he is struggling for form.
3. Vincent Aboubakar
Aboubakar has the pace to frighten John Terry and the power to compete physically with any defender on the planet.
His goals record is pretty impressive too – he’s already netted six times in seven club games this season.
2. Alberto Bueno
The former Real Madrid flop revived his career with Rayo Vallecano, scoring 28 goals in 72 matches before signing a big contract with Porto in the summer.
Bueno did his best Robert Lewandowski impression in February, scoring four goals in just 14 minutes against Levante.
1. Iker Casillas
Arguably the best goalkeeper in the world since the start of the 21st century, Casillas was the star stopper at Real Madrid for 16 years and holds the Champions League record for most clean sheets.
With countless records, trophies and individual awards, Casillas could be the most difficult goalkeeper to beat Chelsea will face all season in any competition or league.
Even Lionel Messi has found himself in AWE of the fearlessness and skill of the veteran goalkeeper.
