We cant have summer football because all our clubs would suffer in the last rounds of the euro competitions you know.
After all the spl is a major force in world football you know and no teams ever won a european trophy playing in a summer season......
apart from say
Zenit St Petersburg
Dynamo Kiev (twice)
Dynamo Tblissi (back in the days of USSR)
IFK Gothenburg (Four times)
CSKA Moscow
Shakhtar Donesk
Not forgetting Malmo reaching the European cup final in 1979
