Nigeria's Flying Eagles have called up nine foreign-based professionals led by FC Porto youngster Mikel Agu, to join others already in camp.
Media Officer of the team, Samm Audu said Agu, 19, is a highly-rated defensive midfielder who has been knocking on the first-team door at Portuguese champions Porto for the past two seasons.
Bright Osagie from top Austrian club Red Bull Salzburg has also been handed an invitation by the reigning African champions.
Team secretary Aliyu Lawal Ibrahim disclosed that the foreign pros have been given a Sunday deadline to report to the Flying Eagles training camp in Nanka, Anambra State.
Ten players have also been dropped, while six other players from the domestic league have been given a chance to prove themselves in the team.

Meanwhile, the Flying Eagles will step up their build-up for the 2013 African Youth Championship in Algeria with warm-up matches against several top Nigeria Premier League clubs.
