Lewis Hamilton said Ferrari "definitely have some work to do to improve" as his former Mercedes team-mate George Russell set the pace on the final day of pre-season testing.
The seven-time world champion ended the day sixth fastest in his Ferrari, 0.8 seconds off former Mercedes team-mate George Russell, who ended day three quickest overall.
Hamilton said: "It's hard to know what fuel loads everyone is running so you have to take everything with a pinch of salt.
"(McLaren) won the constructors' (title) last year. We expect them to be one of the quickest if not the quickest. As with Red Bull, they dominated for many years. We've definitely got some work to do to improve."
