Froome, who has won the Tour three times, seems happy to let Porte be the pre-race favourite, and said as much the previous evening.
Former world champion Mark Cavendish has confirmed he will be racing in this year's Tour, following a bout of glandular fever, and will hope to add to his record tally of 30 stage wins in the race.
"This is the biggest race and this is the big goal", Porte said. "It's a different Tour to normal so a few surprises might happen". Points are awarded for the riders who are first over the top of each climb during the Tour.
"I've been at Team Sky since we began back in 2010 and for me it's home", said Froome on the team's official website. In 2013, on a similar stage, the Team Sky machine suffered a brutal onslaught from their rivals, leaving Chris Froome on his own to fight the likes of Nairo Quintana, Alberto Contador and ALejandro Valverde.
While fourth is by no means a awful performance, it was the way in which Froome imploded on the final stage which would have caught the eye of all the general classification contenders.
Improving weather is expected early next week as the tour shifts southward through Luxembourg into northeast France.
It's hard to name just one rival. But it would be nice if Team Sky had a bit more competition this year'.

That would give a total of around €29m, with Andrea Ranocchia, George Puscas and Andrew Gravillon also likely to leave. From this weekend onwards, the 28-year-old will be off the transfer market.
For mine though, a big story out of this year's race will be how Colombian Esteban Chaves (Orica - Scott) fares. I say that because of the lack of mountain top finishes and also the lack of time trial kilometers.
Tour champion Chris Froome, who is chasing his fourth Tour de France title this year, said he had "no trust issues" with Team Sky but said he understood why some cycling fans may be sceptical.
His lack of consistency and ability to have a very bad day on one of the crucial mountain stages has characterised his grand tour career to date.
The red and white polka dot jersey is worn by the best climber in the race, known as the "King of the Mountains". Porte finished a narrowly defeated second, Froome fourth.
The Tour has given me memories that I'll keep with me for the rest of my life. "He's the big favourite here".
"I'd love to be on the final podium but I want to win stages as well but I can not go in breakaways because the peloton would not let me so I would need to have a good day and be the strongest on one of the climbing stages".
On the plus side for the Briton, Froome's ever increasing experience as a Tour victor is a huge advantage. This year, Dimension Data's technical teams work together across four continents via hyperconnected mobile collaboration hubs equipped with the latest digital and virtual workplace technologies. The race starts in Dusseldorf, Germany and cuts through Belgium and Luxembourg before traversing into the legendary unforgiving terrain of France to finish Stage 4.
