The Amadou Onana deal was one that not many outside the confines of Goodison Park and Finch Farm would have anticipated too long ago.
Everton, a club whose financial struggles and issues in making sure they fly underneath the Premier League's profit and sustainability regulations have been well documented, weren't hotly tipped to make too much of a splash in the transfer market this summer.
The early addition of James Tarkowski on a free transfer from relegated Burnley was seen as a good piece of business, the kind of transfer that the Toffees were anticipated to engage in more of as they sought to reduce their spend and wage bill following the exits of Richarlison to Tottenham Hotspur in a £60m deal and the release of big earners such as Fabian Delph, Cenk Tosun and Gylfi Sigurdsson at the end of their deals.
