Arsenal's Premier League rivals Manchester United broke the world transfer record earlier in the week when they paid £89million to Juventus to take Paul Pogba back to Old Trafford.
That deal continues a trend which has seen the record extended by nearly £75million in 20 years, with the likes of Alan Shearer, Cristiano Ronaldo and Gareth Bale previously holding the tag of the world's most expensive player.
Wenger's own record signing came when Arsenal paid in excess of £40million to sign Mesut Ozil from Real Madrid and he has previously criticised the amount of money that has been spent recently.
