Sporting CP are chasing Leicester City pair Islam Slimani and Adrien Silva.
Algeria striker Slimani and Portugal midfielder Silva are both on-loan at AS Monaco this season.
O Jogo says Sporting want to bring both players back to Portugal for next season. Slimani and Silva are former Sporting players.
Sporting know Leicester do not have either player in their long-term plans.
As such, they are confident of bringing the duo back to Lisbon once this season eventually concludes.
