For me, Sidnei Lobo is by far the best Assistent Manager in the game and on 2nd place I put Oliver Bierhoff. I had Sidnei Lobo on my Barcelona save and he is absolutly tremendous. Good advice, good responses to press conferences (when I sent him), good opinion about players. Oliver Bierhoff is also a very very good *** Man. When I played as a club that didn't allowed me to sack my *** Man, I brought Bierhoff as a scout, and in the 2nd season I made him *** Man. This way, he had complete knowledge about my players and he is cheap too. Chose any of these two (Sidnei Lobo and Oliver Bierhoff) and I bet my life you won't regret.
