McLaren team principal Martin Whitmarsh turns focus on Ferrari after Fernando Alonso loses ground in title race Hamilton did at least trim 10 points off his own deficit to Alonso after the Ferrari driver failed to finish, but it was a challenging weekend all round for the Woking-based team. The race was the first since Hamilton's move to Mercedes was confirmed and that, understandably, was the major topic of paddock discussion, even allowing for Michael Schumacher's retirement announcement. And he completed the weekend by taking Button to task on Twitter, having been led to believe his team-mate had stopped following him on the social media site. In a series of tweets on his official feed, which has around 1.1 million followers, Hamilton said: "Just noticed @jensonbutton unfollowed, thats a shame. After 3 years as teammates, I thought we respected one another but clearly he doesn't. Funny thing is, we are STILL teammates! All good tho, I plan on giving this team & fans all I got til I cross the finish line in brazil!!! But the 27-year-old was left embarrassed when he realised Button did not follow his Twitter account in the first place. Hamilton's comments are unlikely to have impressed Button and could put a strain on a working relationship that, while seen as being largely harmonious, has been known to be tense. At the Belgian Grand Prix he posted a picture of the telemetry from his and Button's qualifying laps, which the team quickly told him to remove due to the sensitive nature of the data, on that occasion Button said he was "disappointed." On the track things were not a great deal better. Having had the quickest car at the previous four races, McLaren will have been concerned about how Red Bull turned the tables to dominate in Japan.
