Mesut Ozil for £42 million, Alexis Sanchez for £35 million, Petr Cech £11 million; for years now Arsene Wenger has been gradually tinkering with an Arsenal side that have become extremely frustrating to support.
Since 2013 the shackles have been taken off and they have been free to spend, but which transfer has created the biggest frenzy amongst fans and pundits?
Off all three, it is the transfer of Petr Cech that Arsenal can once again seriously complete for the Premier League title.
“If you're looking at the front players of the top four, I think Arsenal have the best options,” said Robbie Savage, who was speaking at a BT Sport media event to launch the broadcaster's football coverage for the coming season. "Arsenal now have plenty of options, quality in numbers, Walcott down the middle, then [Olivier] Giroud, [Danny] Welbeck and Sanchez”.
"The teams around them don’t have a wealth of quality in the same way. If [Sergio] Aguero gets injured for City then I worry about them. If Costa’s out for Chelsea they've got [Loic] Remy or [Radamel] Falcao and I worry about that and at United if [Wayne] Rooney gets injured whose going to play up top."
What Arsenal have gained in signing Cech is a serious upgrade on Wojciech Szczęsny. Rio Ferdinand, who this season will be working full-time as a football expert and presenter for BT Sport, spoke of the affect having an experienced 'keeper can have on a side.
He explained: “You think right, I've got the man in behind me now, I can concentrate on my own game, rather than second guessing the keeper a little bit”.
