Yes. I am. Look around, 50mil is expensive, but not really outrageous for winger (there ain't many good ones, let alone one available). What
@Womp said, who are other wingers with similar profile? That's your own expectation projecting about better value & potential while you can't agree with how Perisic become a main target for Mourinho. There are enough debate that Perisic being one of better winger at the moment.
Age is not always an only case to judge length of player's contribution. Jones, Ando & now Shaw have talent & age on their side, yet it can come to a point where there is doubt about possibility those players can fulfill their potential. There are many factors can affect a player career. Perisic pursuit is clearly to get thing going this coming season. It's not about signing a potential & wait few more years. There is long term planning, but dealing with what's coming is still the main focus of football. There is situation, you can't wait but to act accordingly.
Agree to disagree completely about Abramovic is justified acting the way he did. Support the board to sign dross like Baba, that now Sunderland CB. Suspect Salah, Cuarado were in the case too. We now know the board backed by Roman was the one who had the say in selling Lukaku, not as the narrative of Mourinho didn't give youth chance & wanted to sell Lukaku. How Chelsea supporting youth since Mourinho's sacking?
