Porto contract rebel Moussa Marega has reportedly refused to sign a new contract at the Portuguese club, leading to several Premier League clubs to chase his signature.
The main club interested in his is West Ham United, after the Mali international refused the most recent contract offer at Porto.
The 29-year-old's contract ends next summer, and he reportedly wants a move to the Premier League.
Instead of losing him for free next summer, Porto are looking for potential buyers this summer, leaving the Hammers with a chance to pick him up for a bargain fee.
With West Ham already selling Albian Ajeti and Jordan Hugill, leaving David Moyes with Sebastien Haller and Xande Silva as their only two recognised strikers.
Reports claimed that West Ham had a loan move for Marega rejected in January.
Tottenham Hotspur are reportedly also interested in Marega, seeing him as possible backup to Harry Kane.
Marega has scored 60 goals in 145 games for Porto, bagging 15 goals and providing nine assists in 45 games in all competitions this season.
Marega is a fast, powerful striker, that could adapt to the high intensity of the Premier League, being touted as similar to Romelu Lukaku in terms of play style.
