"Honestly, I think they've slowed down quite a bit from the beginning of the year," Hamilton said to Sky Sports.
"I mean, just like other DRS they don't have the DRS advantage all of a sudden than they used to have. Where did that go?
"So yeah, but I mean they've just had an upgrade. So with all due respect to them, for them to not have extracted that in qualifying is interesting, but I think in the race, they're still the quickest and I think it'll be very hard to beat them tomorrow.
"But yeah, we are just as surprised as everybody else. But definitely interesting to see some, you know, see some of the deficits and how it's changed from race to race and how we've all closed up. Super happy to see the McLaren up there."
