Hamilton finished the race in P8, just behind his team-mate George Russell, but the 39-year-old believed he could have achieved more this weekend.
“If I just qualified, like I should have qualified if I didn't have a problem, I think I had the pace today to definitely be in the top five,” Hamilton said to the media including GPFans.
“If I started fourth, I would have finished fourth. I was surprised when I drove through and saw the Ferraris in P3.”
“We made a big set up change for FP3 but then it was wet so we didn't get to test it. Today I took out a bunch of wing to balance it and it was fine.”
The champion also revealed how difficult it was to execute the two stop strategy and provided an x-rated assessment of his weekend.
“I had a lot of fun today. I started on the soft tyre. I think it was a very good tyre. I felt much better than my medium tyre. The hard tyre was pretty decent.
“It was really difficult to see what I needed to do, maybe push for it, but I was on a two stop, so trying to use up the tyre, but I also wasn't sure whether or not we might possibly go for one [stop].
“Probably, if I'd done one stop and managed to manage a little bit better, we could have done a one, maybe finish one spot ahead.
“I look forward to next weekend because I had a s**** weekend this weekend.”
