#2 Moussa Marega
The Mali international signed for Porto in January 2016 but failed to make an immediate mark at the club. That prompted Porto to loan him out to Vitória Guimarães. However, six months into the move, Porto are already regretting after seeing his amazing showings for his new team this season. The on-loan Porto forward has scored 10 goals from 13 Liga games this campaign, a goal tally that is bettered only by Bas Dost and his Porto teammate Andre Silva.
Marega was the subject of interest from a number of Premier League clubs in January and going into next summer, there is not much of that plummeting. He might not have got his chance at Porto and after a fine season with Vitoria, the temptation of playing Premier League football should be enough for the 25-year-old to part ways with Porto in the summer again.
