Manchester City are watching Porto pair Yacine Brahimi and Alex Sandro.
The Daily Mail says City sporting director Txiki Begiristain checked on Porto pair Yacine Brahimi and Alex Sandro on Tuesday night.
Begiristain, who also wants Wolfsburg's former Chelsea midfielder Kevin de Bruyne, watched Porto in action against Bayern Munich having sent scouts to watch them in the first leg in Portugal last week.
Sandro, a 24-year-old Brazilian left-back, is wanted by Juventus too while Paris St Germain and Bayern have an interest in Algeria winger Brahimi, 25.
