The Algerian international was in sensational form last season, netting 31 times across all competitions and finishing up as the second-top scorer in the Primeira Liga.
Accordingly, the 28-year-old has been linked with a number of Premier League clubs this summer.
The Sun mooted Everton and Southampton as potential summer suitors earlier this month, amid news that Slimani had handed in a transfer request at Estadio Jose Alvalade.
Meanwhile, West Bromwich Albion are believed to have tabled a club-record £21million bid for the African attacker, who measures in at 6 foot 2.
And in a boost to the efforts of the aforementioned trio, Record now claim Slimani’s ‘head is in England’, with the 43-cap forward eager to complete a Premier League transfer.
However, Sporting are still holding out for their £26million valuation.
