Gaël Etock is set for promotion at Sporting Lisbon.

Chelsea have an option on the former Barcelona junior, having been part of negotiations in his move from the La Masia academy to Sporting two years ago.

The Cameroon teen has been starring for Sporting B in recent games and coach Jesualdo Ferreira is now considering calling him up for their massive clash with Porto.

Etock is expected to eventually move to Chelsea once he gains a European passport.
