Manchester City had scouts at Wembley to make a check on Sporting Lisbon defender Daniel Carrico.
Carrico skippered Portugal U21 in their 1-0 defeat to England on Saturday.
His assured displays at the heart of the Sporting rearguard have caught the attention of Eastlands boss Mark Hughes. Carrico's current contract does not expire until July 2013 - but the right-footed defender does have an £18.4m release clause.
City are also keen on Rio Ave fullback Fabio Faria, who also featured on Saturday.
