Everton will have to pay a massive €50m (£45.85m, $58.8m) fee if they want to attain the services of Benfica forward Raul Jimenez.
Despite the arrivals of Wayne Rooney and Sandro Ramirez, the Toffees are still looking for an additional striker to spearhead their attack following the departure of Romelu Lukaku to Manchester United.
Manager Ronald Koeman said following Everton's 1-1 draw at Manchester City that if the club wanted to compete with other squads, that they would "need a striker in as well" along with other notable positions.
Previously linked with a loan move for Chelsea's exiled striker Diego Costa, Portuguese publication Record now reports that Everton have had a €30m (£27.5m, $35.3m) offer rejected for Jimenez.
The Portuguese champions instead believe they can receive a fee of €50m for the former Atletico Madrid striker, having previously received a similar offer from a Chinese club back in the January transfer window.
"There was a good offer economically for Benfica and for me also, but the important thing is that I decided that I want to stay in Benfica," Jimenez said after he rejected the move in January.
"I am very happy and in Europe I can continue to grow as a player, because I believe I have a promising future. What I want is football glory before money.
"The fans of Benfica always treat me very well and support me. When I go out on the street they recognise me, they tell me that I am doing very well. All of this pleases me."
In addition, Everton also face competition from Ligue 1 champions Monaco who are interested in the Mexican international. The same report claims Leonardo Jardim's side have also had a €30m bid rejected for Jimenez as they prepare for the potential departure of Kylian Mbappe.
It remains to be seen as to whether Jimenez is worth the steep price tag slapped on him by Benfica, let alone whether a European club is willing to lodge a bid as the 26-year-old has only scored 12 league goals since the start of the 2015/16 season.
The Tepeji native also notably had a disappointing spell at Atletico Madrid, scoring just once in 27 games in all competitions during the 2014/15 season. However, with options running out at this point of the transfer window, Everton may need to stump up the extra funds.
