Hamilton and Leclerc pitted under the safety vehicle, re-joining the track in 1st and 4th place respectively, while Bottas, Verstappen and Vettel had already pitted before the safety-car period.
"Harry, you don't know how much this message means to me buddy", he wrote.
"Yesterday, it was a bit of a nightmare", he said.
"But certainly once I was in free air I felt quite good and the pace was quite strong, also in comparison with Max [Verstappen]". "On my side I just didn't put the laps together - the last couple of laps in Q3 particularly just weren't strong".
The rumours began to circulate when Mercedes boss Toto Wolff suggested that Hamilton might look to finish his career with the legendary Italian team.
Five times world champion Lewis Hamilton says Mercedes should not be blamed for their dominance and he would far rather be in a battle with Formula One rivals Ferrari and Red Bull than teammate Valtteri Bottas. I had the laptop on my knees watching the game when we saw Liverpool beating Barcelona. I love that. Especially when we're kind of intertwined.
".It's awesome. But when that's not there, it's definitely a lot less exciting from a competition point of view".

We made such big steps. "As long as Manchester City are around with their financial power, no team will pass them easily", Klopp said.
Lewis Hamilton moved to the top of the drivers' championship as Mercedes dominated again in Barcelona, but some of the talk in paddock was less promising for Silver Arrows fans.
"When you are in negotiations you throw in the Ferrari name", he said. Whether the correct call or not, it's surely not something the drivers will be happy about having to get used to, and it appears Ferrari are already in two minds about how on earth to close the gap, not only to Mercedes, but the form Verstappen.
Binotto said there was much for Ferrari, who brought upgrades to the first round of the traditional European season, to learn.
"Even within the team we have discussed it and with Lewis we have discussed it and we have agreed on the topic", added the Austrian.
Hamilton experienced firsthand what an overzealous rivalry between teammates can lead to when he and former Mercedes driver Nico Rosberg knocked each other out on the first lap at the 2016 Spanish GP. Only Michael Schumacher has more with 91.
However, Wolff made clear that Hamilton has not expressed any desire to leave Mercedes.
"I think power-wise, straight line speed, we are good enough but certainly we have some weaknesses on the auto that were highlighted this weekend".
"And if one day ways part, it will be very positive and each of us will try to achieve success with a different setup".
