Yes there is; you just have to be careful how you answer questions in press conferences. Jose Mourinho is fairly easy to manipulate; if he's on a good run you can make him (and his squad) complacent by praising them, and if he has a poor record against you you can needle him and get him to whip his players into a frenzy. I managed to maintain a winning streak over Chelsea for four seasons and they finished most games with ten men or fewer (naturally the streak broke in the CL final, but how could it have been otherwise).
