Sorry, didn't mean to compare the two as it's apples and oranges, more that you can't stick with somebody just because you may have made an error in re-signing him, or not cutting ties at the end of last year.

At some point all clubs with all coaches reach the end of the line for varying reasons. We shouldn't be over committing to anyone and need to be prepared to make hard calls whenever they're needed, whether that's next week, in three months, or in 3 years.
