A host of Premier League clubs had scouts posted to Benfica's clash with Porto.
A Bola says Manchester United, Chelsea, Liverpool and Arsenal were among the big European names who had scouts present at Benfica's clash with Porto.
O Classico is the biggest game in Portugal — but a selection of top clubs around the continent sent representatives there for business not pleasure.
As well as the Premier League quartet, up to ten more teams had scouts present for the match.
Among the list of players expected to court interest from the giants of Europe will be the Eagles' defender, Victor Lindelof, who is known United target.
While , Arsenal scouts are thought to have been present to watch Andre Silva, who they are looking at should they lose Alexis Sanchez and Mesut Ozil in the summer.
Porto striker, Francisco Soares, has been a revelation since joining in January, and his goal scoring exploits will have surely put him on the radar of Europe's elite sides.
