Barca keeping tabs on Andre Silva
Spanish champions Barcelona were keeping a close eye on highly-rated Porto striker Andre Silva. The teenager is also on the radar of Arsenal, Chelsea and Manchester United.
Silva, 20, has transformed into a key player for club and country this season netting 13 goals in all competitions.
According to reports in Spain, Barca scouts were spotted watching Porto's 1-0 Champions League win over Club Brugge in midweek with Silva being one of the players in focus.
The Portugal international was rewarded with a fresh five-year deal over the summer which includes a hefty £52m release clause.
And this is likely to make things tough for Barca, who are in a tight fix with regards to their transfer budget for the campaign.
Barcelona are currently second in the league standings, two points adrift of rivals Real Madrid.
