car keeps pushing to the left when not holding the steering

Hello guys,

I have a fiat punto 2002 1.2 16V with 30 000miles.

So this what happened to me last night. I was driving and got to close to the curve and ended up busting my tire. However this aint the whole story, my car, when driving, keeps driving itself to the left. This would make sense since it was the left wheel that got damaged for me. I changed the tire and put on the spare but the car when driving does not drive straight for me but instead keeps shifting itself to the left. Any suggestions to what happened to the car?

Would greatly appreciate any suggestions and solutions to what may be causing the car to keep shifting left when not holding the steering wheel.

Thanks in advance
