Is there any Sense in the Messi Mess?I'll try to keep this short - just to keep it as a record of what has happened and how the betfair exchange markets have followed.

1. Rank the remaining fixtures. 2. Play the most relevant next. 3. Check the table if all "battles" are mathematically decided then stop, else repeat from 1.
It may even increase the fairness as the most relevant matches are prioritised.  It is more likely that you get a fair run in where Villa and Brighton both play Liverpool full strength and less likely the case where …
