Carlos Sainz believes Ferrari will have to make "compromises" heading into qualifying at Suzuka tomorrow after today's wet running.
With the impending threat of rain set to hit the track during the Japanese Grand Prix on Sunday, Sainz believes the team will need to "think twice" about their setup direction to ensure they can maximise their performance.
"For sure there will be some compromises to be taken, definitely that the rain threat for Sunday looks likely so there's gonna be a few things to think twice about when we're doing the qualifying tomorrow," he told media.
"I think it's going to be an interesting weekend ahead with the combination of the dry track tomorrow in qualy, pushing flat out, and then having that rain threat [on Sunday]."
Teammate Charles Leclerc only completed 26 laps between both FP1 and FP2, in the latter session getting caught up with brake problems.
Sainz said the team were still able to learn something from the conditions and utilise the time to get some testing done, particularly after struggling at Singapore last weekend.
He added: "At least the conditions were pretty consistent out there today. When it's wet, that allows you to do a couple of tests we never get to run [usually] in these conditions.
"That's why it was important for me after a difficult race in Singapore in these conditions to really try and get back on top of the car today in these wet conditions and see if I could find my rhythm again."

Red Bull quick everywhere
Sainz says Red Bull will still be their main rivals this weekend despite the quick pace shown by Mercedes in FP2 on the Intermediate tyre runs.
He explained: "I think Red Bull are quick everywhere: wet, dry, slow, fast circuits, straights, low speed, they're quick everywhere with the package they have now.
"But we are also very quick, so it will be a matter of who nails the weekend and have that two tenths advantage over the other."
