If McManaman stayed he would have won nothing and I don't look at him as an all time great, because he never was.
Coutinho went on win exactly what we won when he was gone and more. So, I have no issue with him leaving either and it's a bad example.
But Owen...now that's someone I rarely reminisce about.
The problem is, every player top class player that left Liverpool in his prime more or less did well. So there are no lessons learned here.
Alonso, Mascherano, Torres, Suarez, Meireles, Sterling etc. all went on to win a bunch of shit.
So I guess the lesson is, leave Liverpool if you want to win shit.
I can't really think of a top class Liverpool player in the last 20 years that left in his prime and didn't win shit.
