Leicester failed in a bid to sign Islam Slimani in January, Diario de Noticias reports.
The Portuguese media outlet claim that five teams made bids for Slimani in January, but by the end of the window he remained at Sporting CP.
The Algerian international striker, a prolific goalscorer in Portuguese football, was the target of Leicester, Everton, Crystal Palace and Newcastle United, as well as Schalke 04 of the German Bundesliga.
All five clubs made offers for Slimani, but no one could match the asking price set on the Algerian’s head.
The details are only clear about Leicester’s offer, which the report claims was the smallest bid submitted.
It is stated that the Foxes made an approach worth roughly £11.4 million (€15m).
It was reported last week by France Football that Everton’s bid was worth £13.7 million, and that same report claims that Slimani has a £23 million release clause in his contract.
Neither of those offers came close to matching the release clause, and clearly neither did Crystal Palace nor Newcastle.
Slimani is clearly rated highly by a number of Premier League sides, and it would be no surprise for him to finally get a move to England in the summer transfer window.
