Interviewer:Rafa,why was Gerrard subbed? Rafa:I have already explained it. Interviewer:Hmmmm...But if you had subbed Momo instead of Gerrard you would have got 2 brains in the field. Rafa:I put the new brain so that the new brain would offer something different from the other brain.If both brains were on the pitch maybe our play would still be dictated by the other brain as the new brain could be over awed by the presence of the more senior brain who is also apparently the newer brain's idol. Interviewer:Oh,I see.Rafa you are a genius.
