It's becoming more common, but it's still quite rare for genuine top quality players to be available - and when they are, you have to move quickly.
Arsenal have been great at that recently, snapping up Mesut Ozil and then Alexis Sanchez for big money in successive summers, and we've been presented with another opportunity this week to sign another world class game changer.
Radamel Falcao has been told he can leave Monaco on loan, and with Real Madrid cooling their interest, Arsenal are clear to grab him.
But for some mad reason, Arsene Wenger is not keen on bringing in the Colombian. It's bonkers.
Falcao will be expensive, of course. His wages are about £8.5million a season and Monaco want a £11.5million loan fee on top of that. It's a total package of £20million to have him for just one season. But it's worth it.
He's a lethal striker with genuine superstar quality. He's a game changer, a big match performer and a total handful for any defender.
With Olivier Giroud out until the New Year, a quality striker is absolutely needed - and there are not many better than Falcao.
Wenger needs to bite the bullet, be brave, be bold and bring Falcao in. It could just be the best decision he's ever made.
