The Mali international has hit the ground running with 14 goals and two assists in 16 Primeira Liga appearances for the Portuguese side so far this season, helping the team to lead the division by two points over Sporting Lisbon. This scintillating form beats his prolific loan spell for Vittoria last season, where he scored 14 goals in 31 appearances before returning to Porto's starting XI in the summer.
It is no surprise then that Europe's top teams are keeping a close eye on the African striker, with reports indicating that Manchester United and Chelsea have expressed interest in the 26-year-old.
Manchester United have struggled infront of goal this season with Romelu Lukaku only netting 10 times so far, despite his excellent start. Meanwhile in London, Chelsea have often relied on inconsistent summer signing Alvaro Morata, who has only scored 10 goals as well.
With the race for the top four heating up, it could come down to a matter of goal difference. If either team could succeed in signing Marega, it could definitely help their chances.
