Arsenal had scouts posted to see Porto's clash with Benfica.

O Jogo says the Gunners' scout was in attendance to run the rule over a number of possible summer targets.

Wenger has previously admitted his interest in Porto striker Jackson Martinez, who is heavily tipped to be leaving in the summer.

However, his team-mate Yacine Brahimi and Benfica's Anderson Talisca were also on show and of interest to Wenger, it is claimed.
