Shortness of breath during soccer including discolored phylem this affects my performance no matter how fit I am always short of breath after 10mins?

Shortness of breath. You should be evaluated by a doctor. You could have exercise induced asthma. This is easily manageable and you can still enjoy playing soccer!
Exertional Symptoms. Exertional symptoms such as shortness of breath can be caused by something as mild as an allergy or exercise induced asthma or as serious as heart disease or lung disease. You should be particularly concerned if younger family members have unexplained sudden death. This is worth a trip to your doctor for further testing.
