Pierre Gasly believes Fernando Alonso has changed his approach and is being more aggressive on track than he was before announcing his retirement from Formula 1.

Alonso announced during F1’s summer break that he would not race in the category in 2019 and has since confirmed he views the move as retirement. Having been involved in an incident with Kevin Magnussen during qualifying at the Italian Grand Prix on Saturday, Alonso then collided with Gasly after the Safety Car restart in Sunday’s race and the Toro Rosso driver believes it’s a sign of more aggressive driving from the Spaniard.

“Basically, we came to Turn 1 after the Safety Car side-by-side and I went on the outside and [Alonso] pushed me completely out of the track,” Gasly said. “I tried to stay on track as much as I could but he didn’t leave me the space so I had to jump over the curb and then he also touched me and completely damaged the right side of my floor.

“From there on from Lap 8 or something the car was completely broken and I was sliding everywhere. We knew it would be really difficult.

“I think his approach is a bit different because he knows he is not going to be in Formula 1 next year so it looks like he is behaving more aggressive than we was before. [In Monza] for me what he did was not fair — we know that if you are alongside you need to leave space for one car and today he didn’t. I know he doesn’t like us [Toro Rosso] because we have the Honda engine but nevertheless when you race with drivers you [must be fair].”

With Max Verstappen being penalized for contact with Valtteri Bottas when defending at Turn 1 late in the race, Gasly says he sees no reason to bring up the collision in the next driver briefing.

“About the incident with Fernando, no I think it is something we can talk together but I am not a guy to make a big story out of these things. If I have something to say I will tell him face to face.

“It is difficult but clearly we can see some inconsistencies. From the inside it didn’t look fair at all but I need to look at the images again. Clearly after that incident my race was over and then his race was over a couple of laps later.”
