Alpine team principal Otmar Szafnauer is "confident" the ruling over Oscar Piastri's contract will fall in their favour with the dispute set to go before the Formula One contract recognition board (CRB).

Following Fernando Alonso's decision to leave Alpine, the team announced that reserve driver Piastri would replace the Spaniard for the 2023 season.

However, the Australian contradicted this claim when he released a statement on his social media platforms, stating that he would not be driving for Alpine the following year.

Piastri is understood to have committed to McLaren, who are not commenting publicly on the matter.

But speaking ahead of this weekend's Belgian Grand Prix, Szafnauer is adamant Alpine had all bases covered when securing his services.

"We will have the CRB decide which contract Oscar signed takes precedence and after that, we will see where we go," he said.

"There are certain things that need to be in the contract [to secure Piastri], and I am confident they are in there.

"Once we have all the information in front of us, we will start looking at who will fill the open seat."

However, Szafnauer did accept Alpine were hasty with their announcement, having raised eyebrows by doing so without a statement from Piastri.

"I told Oscar before the announcement was made," Szafnauer added. "He happened to be in the simulator, so I went and found him. He smiled and was thankful, so we made the release very quickly.

"Things happen very quickly. We too reacted quickly and didn't want to go back and forth with his management, which is why we put the release out."

Red Bull's Sergio Perez conceded it was driver error that forced his crash in qualifying for the Canadian Grand Prix, which will see him start from a lowly 13th on Sunday's race in Montreal.

Perez, who sits second in the driver's standings behind team-mate Max Verstappen, put his Red Bull into the wall at turn three during Q2 on Saturday, forcing out the red flag and ending his hopes of a front-row finish.

Verstappen handled the wet conditions best, meanwhile, finishing almost seven tenths of a second quicker than Fernando Alonso, who qualified second in his Alpine.

After a disappointing qualifying finish, Perez claimed Sunday's race will be about damage limitation from his standpoint.

"I did a mistake from my side, so I'm very sorry for my team," Perez told Sky Sports F1 post-qualifying. "I let them down unfortunately, but I'm going to already be thinking on tomorrow, and hopefully I'm able to recover and get into strong points.

"I wasn't struggling with the brakes, I think they were on the cold side. I had a lock-up into turn 10 the lap before. I flat-spotted them, and it probably meant that I was a bit out of shape and going into turn three I just became a passenger. As soon as I touched the brake, it was a bit too much.

"It can be tricky and difficult, but it was just a mistake from my side. Tomorrow I will just try to minimise the damage and just attack from lap one onwards, and see where we end up."

On the other hand, Alpine team principal Otmar Szafnauer cited driver quality as the reason Alonso was able to qualify in second amid tricky conditions.

Both Alpine cars progressed to Q3, with Esteban Ocon also finishing in seventh but he was out-qualified by nearly two seconds by Alonso, who was without fear in the wet.

"We've had good pace here all weekend," Szafnauer told Sky Sports F1. "We had decent pace in Baku too, so we keep working on the car, but Fernando's experience and skill shone through today, and put it on the front row.

"He's always been really, really good at adapting very quickly, so he's always on the pace very quickly. When you have changeable conditions, that ability to adapt quickly shines through."
