Talented Nigerian striker Oghenekaro Etebo is a target for Arsenal.
The Sun says Leicester City are also interested in the Feirense player.
The Premier League duo sent scouts to watch the 21-year-old in action for Portuguese side Feirense in their 1-1 draw with Porto on Thursday.
Etebo made a name for himself in Rio during the summer when he became the first player in 44 years to score four goals in an Olympic fixture in Nigeria's thrilling 5-4 win over Japan.
He was also crowned African Football's Most Promising Talent award in 2015 in which he has the chance to defend this year.
