have rejected Tottenham's initial offer for star midfielder Adrien Silva, according to reports in Portugal.
The 28-year-old, who came close to a move to Leicester City last summer, is once again being lined up for a potential move to the Premier League.
Tottenham have been keeping a close eye on the Portugal international over the last season, but have failed with their opening offer.
According to O Jogo, Sporting have made clear their financial demands for Silva, having rejected an initial offer of £17.5m plus a further £4m in bonuses.
It has been claimed that the Portuguese giants are looking for closer to £27m for their star asset, plus the £4m in bonuses Spurs have already proposed.
