I have a list that looks like so:
['Man City', 'Chelsea', 'Man City', 'Man City', 'Man City', 'Man City', 'Chelsea, Real Madrid, Sevilla', 'West Brom, Sunderland, PSG', 'Man City', 'Man City']
However, I want to change it so the strs with multiple teams become a list within the list
['Man City', 'Chelsea', 'Man City', 'Man City', 'Man City', 'Man City', ['Chelsea', 'Real Madrid', 'Sevilla'], ['West Brom', 'Sunderland', 'PSG'], 'Man City', 'Man City']
