There is an element of risk, spending 100m or more, but we have dropped out of the top four and look likely to repeat that unless we start buying the best players we can.
Ozil and Sanchez have been our best players and it's no coincidence that they were the most expensive.
We have accumulated almost a whole squad of good players but very few are more than that, yet several are being paid top players wages which isn't reflected in their performances.
So it might be a lot of money for a striker, but buying several like Perez, Giroud, Welbeck, etc, and paying them around 300k a week between them clearly hasn't worked.
When was the last time we bought a striker that really gave the club a buzz and got the supporters excited?
I would rather take a chance on Mbappe just to give everyone a lift and fail, than do the bare minimum where we know we aren't going to really challenge.
I know it's not going to happen but I would have no problem with us spending that amount on a striker.
It worked with Ozil and Sanchez when we spent big, so maybe spending big means you get a better quality player.
