Where did you get that idea? Did we have a replacement for Ronaldo in place when we sold him? Err, No, and that is despite being fully aware that he wanted for leave for 2 seasons before he eventually left.
We didn't replace Tevez when he left either. We played a full season before signing Hernandez. Did Newcastle have a replacement lined up for Andy Carroll before Liverpool inexplicably paid £35m for him?
by the way at Liverpool. Look at how that turned out, Newcastle took the money and waited until the summer to buy a replacement, they now have 2 strikers who are both better than Carroll, and for half the price they sold him for.
How is that pointless again?
Nah mate when someone offers silly money you take it 99 times out of 100. I would agree you shouldn't leave yourself struggling to field players for that position just to sell, but we are not short of options for that area.
We already have Evans who did a fantastic job filling in during Vidic's absence last year. If someone is stupid enough to offer £40m for a 30 yr old CB who has just been out for a year, personally i would bite their hands off, and worry about a replacement later.
