Chris Coleman likely to be named as the next Sunderland manager.

Quite why a manager who was quoted as wanting to manage a Champions League team earlier in the week would want to manage Sunderland...

Either way his stats (which I often base my judgements on for managers), is currently at a win rate of 34%.
This includes his successful spell as Wales manager.

Anyway. Assuming he maintains that success rate over the next 20 games, expect Sunderland to be relegated.

Blackburn went down on 51pts last season. 
I think Sunderland will be lucky to exceed 40, including the circa 20 Coleman should pick up as a minimum.
