Atletico Madrid set to smash record transfer fee for a signing and a sale LaLiga Griezmann and Joao Felix will enter the club's history books

The summer of 2019 will be anything but business as usual at the offices of the Estadio Wanda Metropolitano as work continues to rebuild the Atletico Madrid squad ahead of next season.

Lucas Hernandez was the first player to confirm his exit, to Bayern Munich for 80 million euros some time ago, while only one addition has been confirmed in 20m euro signing Felipe Monteiro.

The club expect more business to be done and that could set new records, with Joao Felix being linked in what would be the club's most expensive ever signing if Benfica insist that Los Rojiblancos pay the 19-year-old's 120m euro release clause.

That same fee will be how much Antoine Griezmann will cost Barcelona when his release clause drops to that price on July 1, setting the club record for their most lucrative ever sale.

Joao Felix would surpass Thomas Lemar

Atletico are heavily focused upon one key deal in particular this summer: Joao Felix.

Should he join Los Rojiblancos, he would beat the 72m euros which Atleti paid to sign 70 percent of the rights of Thomas Lemar from Monaco last summer.

Both players would line up alongside each other, as well as the club's third most expensive addition, Diego Costa, and possibly even the fifth, Vitolo.

The top 10 are completed by the likes of Radamel Falcao, who more than justified his fee, and Jackson Martinez, who was a spectacular failure.

Kevin Gameiro, Griezmann, Nico Gaitan, Sergio Aguero and Diego Forlan also enter the list in a selection of the club's best forwards, though not all reached such heights as Gameiro and Gaitan prove.

Griezmann, the first sale for over 100m euros

Lucas Hernandez is the club's current record sale at 80m euros, but his reign will last just a few months after he replaced Falcao with that mantle, who left for Monaco in a 45m euro deal.

Griezmann will top the list at 120m euros, though others to be included in the top 10 are fellow forwards Aguero, Jackson, Costa and Fernando Torres.

Arda Turan, Theo Hernandez and David de Gea add to the list, though should Rodri Hernandez leave for his 70m euro release clause he would become the fifth homegrown player in the top 10 sales, entering in third place.
