Lewis Hamilton thinks there is plenty more to come from Red Bull this weekend, after the Austrian outfit were blighted by reliability issues during Friday practice for the F1 Emilia Romagna Grand Prix.
While the 36-year-old was slightly slower than teammate Valtteri Bottas in both Friday sessions, Hamilton managed to achieve several clean runs without issue.
Red Bull, by contrast, will end the day enormously frustrated after a driveshaft issue caused Max Verstappen to miss most of FP2. It is for this reason that Hamilton isn't getting too carried away by his good pace relative to the rest of the field.
"We started off with a really good setup," Hamilton told members of the media, including RacingNews365.com.
"And just small tweaks here and there, but nothing major. No major issues. So far, good pace for us."
"It's quite bumpy here, but good grip, and the tires are working really well here. I don't think we've seen the best from the Red Bulls yet. I think they look like they've had quite messy sessions with traffic. So it'll be interesting to see tomorrow just how quick they are."
One possible area where Mercedes may feel more confident heading into qualifying is down to the cooler conditions.
As the British driver observes, the milder temperatures at Imola could make tyre management a much simpler task when compared to the last race at Bahrain.
"The last place we were at in Bahrain, it was so warm. So when you go out and get ready, the temperatures are going up," Hamilton continued.
"They're overheating throughout the corner, from entry to middle to exit at each corner [In Bahrain]. Whereas here you're kind of in a nice sweet spot with temperature. So it's not so bad."
