If you haven't been with us so far this weekend, there are a host of Ayrton Senna tributes, 30 years on from his passing at this circuit. Gasly has a Senna-esque helmet which looks fantastic!
Pole for Red Bull and Verstappen is by no means a given this weekend. The team has yet to top a session, with the Dutchman struggling for confidence behind the wheel.
Perez's incident was rather more subtle than the Spaniard's, just knocking the front wing at the Variante Alta. He will have no issues in taking to the track.
Both Alonso's Aston and Perez's Red Bull have just returned to the pits, so the respective teams are getting them back in the garages for a race to repair them for qualifying. They've got two hours and 15 minutes. Ready, set, go!
Piastri has been noted for the near-miss with Gasly and Leclerc, while all three of Ricciardo, Tsunoda and Magnussen have been noted for their incident a little later.
That messy end to FP3 didn't really reveal what is to come in qualifying. A McLaren 1-2 and a Ferrari 3-4 shows they'll be in the fight for pole, but will Red Bull or Mercedes join that tussle? And will Perez and Alonso have their cars repaired in time for quali following their crashes?
On Magnussen's final lap he had to take to the grass out of Acque Minerali as both RBs were dawdling in front of him. That one might be looked at by the stewards.
Norris is the only driver to improve on that messy end to FP3 and he goes second fastest - 0.3s off Piastri. It is a McLaren 1-2 at the end of practice.
Leclerc, Gasly and Piastri come so close to tripping over each other in order to start a lap before the chequered flag. But half the field won't get a lap in, including Russell, Verstappen and Hamilton.
But a queue at pitlane exit means everyone might not have time to set a lap time before the chequered flag comes out. The two Ferraris at the back of the pack are racing each other in order to get around in time.
Replays reveal what happened to Perez. The Mexican took too much kerb going into the chicane and that unsettled his Red Bull and left him out of control and nudging the wall with his front wing.
The Red Bull driver has gone off coming out of Variante Alta - he reports he is OK. That has wrecked everyone else's soft tyre laps so we go into quali largely blind of the pack's pace!
Stroll moves up to seventh with his final soft tyre run ahead of qualifying. There is a queue coming out of pitlane and everyone coming out has fresh sets of softs on. Pre-quali coming up!
Those on track, Bottas and Sargeant, break into the top 10 in ninth and 10th respectively while a few moments ago Albon moved up to sixth on the times.
A slight lull in the track action as we move into the final 15 minutes of the session. Both Red Bulls and Norris are yet to touch the soft tyres in FP3 so we're keen to see where they stack up.
Hamilton improves but can only climb to ninth ahead of Ricciardo. Tsunoda has snuck up to seventh unnoticed - on the mediums too. That RB looks decent around Imola.
Mercedes looks distinctly fourth fastest again, with Russell seventh and Hamilton ninth following their soft tyre runs. Ricciardo splits them after a solid lap on mediums.
Both Alpines, RBs and Piastri nip out but on a mix of medium and soft tyres, so no full qualifying sims yet. Meanwhile the medical car is parked in front of the Red Bull garage when the green light at the end of pitlane was shown so it is trying to get back in position while the track is live.
Due to the force of the hit the medical car has been deployed to check over Alonso. The car is being recovered by the marshals as Aston mechanics prepare to assess the damage with an eye on qualifying.
Alonso is OK and he has walked away from his Aston that is buried in the barriers. The replays show him losing the rear of his car going into the second part of Rivazza and with the short run-off he plants the rear of his Aston into the wall.
