In the attached file I have outlined the renormalization procedure for a very simple QFT as described in Weinberg's book and it seems that there is a contradiction. I have red some QFT books but I still have this question. Still I believe that this book is by far the most clear book that I have red. Also in order to avoid some answers the origin of the problem starts in the proof of the LSZ formula and the fact that we cannot impose the asymtpotic condition in the strong sense (this is mentioned in some books: Itzykson-Zuber, Magiorre... but the correct proof is not given)
