West Ham United are reportedly keen on the 26-year-old.
According to O Jogo, West Ham United scouts were present to watch Benfica striker Raul Jimenez train at St George's Park last week.
The Portuguese outfit were in London ahead of their participation in Arsenal's Emirates Cup.
West Ham were linked the 26-year-old recently, with O Jogo reporting last week that Hammers boss Slaven Bilic is keen to pair him up with fellow Mexican hitman Javier Hernandez, who joined from Bayer Leverkusen this summer.
And the same publication has now reported that scouts from the East London club watched Jimenez - who managed seven goals in six starts for Benfica last season - train ahead of the club's stint in the Emirates Cup, along with representatives of other clubs.
Signing another big-money striker would have the Irons faithful in dreamland but it seems unrealistic that West Ham will pay the reported £35 million that Benfica want for him.
In fact, they may have to pay more, given that The Sun reported early last month that Everton had offered £39 million for him and, by virtue of the fact he is not on Merseyside, perhaps even that was not enough to prise him away.
