Arsenal boss Arsene Wenger is having Nacional Madeira defender Ruben Micael watched.

Blackburn Rovers boss Sam Allardyce is weighing up a January bid for Micael, 23, after receiving glowing scouting reports.

However, Portuguese sources say Arsenal, Paris Saint Germain and several Spanish Liga clubs are also chasing the defender.

Arsenal and Rovers were represented at Nacional's 4-2 win at Leixoes on Saturday.
