Mourinho went back to Chelsea and won another Premier League title. Rodgers went back to Celtic and has so far won 4 out of 5 trophies (may be 5 out of 6 after today.) Zidane went back to Madrid and won another title and UCL... I can probably do more if I think about it.

In short, it can go either way.
