Can anyone give me some advice for sports asthma? Inhalors are no good!?

I love playing sports especially football, but I find it really difficult with sports asthma. I had a blue ventolin inhalor but i found it completely useless during a match! I asked my doctor for a different one and she gave me an oxis turbohalor. This inhalor has also no effect on me! I take a brown beclazone twice a day as perscribed. I am 17, eat a healthy diet, dont smoke, not overweight and excercise alot. During a match after about 10mins i almost start hyperventilating and feel as if my lungs are about to explode! When I push myself hard I sometimes get lightheaded. I take the inhalor but get no releif! My doctor told me that these were the strongest inhalors on the market. I really love football and dont want to give up but my asthma makes it really hard to play! If anyone has any tips I would be very greatful!
