Premier League champions Leicester City are keeping close tabs on Islam Slimani and Lucas Perez, according to The Telegraph.
It is no secret that Claudio Ranieri wants to sign back-up for star striker Jamie Vardy and the two footballers appear to be high on his wish list.
Islam Slimani has been in tremendous form ever since he joined Sporting CP three years ago and he has bagged 26 league goals this season.
And even though the Lions are not keen on selling their prized asset, they would reportedly consider offers in the region of £25 million.
Meanwhile, the Foxes are also showing interest in Deportivo La Coruna forward Lucas Perez, another footballer who has enjoyed the best season of his career.
The 27-year-old netted 17 times in 35 La Liga outings for his boyhood club, and he has since been linked with quite a few top sides.
