Sadly Torres is not what he use to be, I'd cash in on him and grab yourself a new striker..someone like Cavani, Jovetic or if you can Falco.
Perhaps invest in some youth too like Rodrigo from Benfica or Ademilson from Sao Paulo.
If you must use Torres though, I had some success playing him as an Advanced Forward-attack with his long shots reduced to rarely. Then you cross your fingers and hope he manages to score.
