Max Verstappen has set the pace in the third and final practice session at Imola, leading McLaren driver Lando Norris in P2 and Sir Lewis Hamilton in P3.
Sergio Perez ended the session fourth on the timesheet, ahead of Ferrari driver Charles Leclerc and Pierre Gasly in the highest-placed Scuderia AlphaTauri.
Carlos Sainz put in a lap time good enough for P7, one place in front of Valtteri Bottas, who topped both the Friday practice sessions.
Fernando Alonso and Esteban Ocon rounded out the top 10, and the Alpine looked more competitive at Imola than at the season-opener last month following the team bringing a raft of upgrades this weekend.
Several lap times were deleted in the session due to track limits violations, so drivers will be eager to stay within the limits in qualifying later today to avoid starting the grand prix further down the grid than possible.
