Lewis Hamilton was Mr. Consistency in the early part of the season after a string of good performances.
Now, like his teammate Jenson Button, his finishing positions have been on the slide.
A third-place start in Monaco should have been a launch pad to attack the two cars in front for the race win.
Instead, the McLaren struggled with the pace of its rivals and slid backwards through the field. Most infuriatingly to Hamilton, Sebastian Vettel popped out ahead of him after his pit-stop.
This prompted Hamilton to complain about a lack of communication from his team, who apparently failed to notify Hamilton that he would have to push hard to keep Vettel behind him.
The 2008 World Champion is out of contract at the end of the year. With Felipe Massa likely to leave Ferrari at the end of the season, a seat could open up with McLaren's eternal rivals.
Red Bull's Mark Webber may move on too after the 2012 season, and Mercedes' Michael Schumacher's three-year return is due to end this year too.
There are options open to Hamilton should he want to get some fresh oxygen with a different team. Though all of the options have big red flags hanging over them.
Ferrari is now Fernando Alonso's team. He and Hamilton had a turbulent time at McLaren in 2007 as the Spaniard was rattled by the rookie Englishman's stunning ability to challenge him at all levels. Would he want to team up with someone who he never really saw eye-to-eye with?
Red Bull would still feature Sebastian Vettel, a very similar driver to Hamilton which could result in a division in a famously tight-nit team.
Mercedes have improved every year since re-entering the sport in 2010, but the team's future in the sport is far from confirmed. Nico Rosberg is a long-term friend from the pair's go-karting days, so this perhaps represents the likeliest landing spot for Hamilton.
It's only six races in and the driver rumor mill has already been sparked to life.
