I am under contract with Sporting and I'm a Sporting player. There is no way I can say I am going to leave. I am fine at Sporting.
However, Sporting has confirmed they rejected a big from Arsenal (via Duncan Castles):

Updates from Wednesday, Aug. 27
William Carvalho is being offered to Arsenal for around £24 million, according to a report from Portuguese source Record.
101 Great Goals summarises the latest on the Sporting midfielder:
According to Portuguese paper Record, Sporting are willing to accept a €30 million bid for William.
Noticeably, earlier in the summer Sporting had seemed resolute to only accept bids of around €45 million for the player (as is the price of his release clause), while recent days have seen O Jogo say that the Gunners could land the player for €30-35 million provided they loan the Portuguese club a player as part of the package.
Arsenal are yet to take any action in their hunt for Sporting Lisbon star William Carvalho, according to the Portuguese giants.
The North Londoners have been linked with Carvalho for some time now, but Pete O'Rourke of Sky Sports cites Sporting in saying that an approach is yet to be made:
The midfield anchorman is known to have a £37 million release clause in his contract, but according to a recent report from Portuguese newspaper O Jogo (h/t 101GreatGoals), he may be available for substantially less.
This is due to a third-party ownership complication in Carvalho's current situation, whereby a Portuguese investment firm Banco Espirito Santo boast 40 percent of the player's rights. Twitter's Messi Minutes provides details of the alleged contract scenario:
Sporting retain a majority stake in Carvalho's services and, more crucially, all of his playing rights, so they would still need to agree any deal taking Carvalho away, but it's believed BES are very much in need of the funds.
Whats more, it's added that Carvalho earns a wage that would pale in comparison to that which he could earn at the Emirates Stadium—a fee which would be considerably less than the £150,000 per week it's thought alternative target Sami Khedira would demand:
O Jogo (h/t 101GreatGoals) reported last week that this had led the Gunners to lining up a €30 million (£24 million) bid for the player, which would be far more acceptable by their usually stringent standards.
The most advantageous aspect for Arsenal would be Carvalho's supposedly much lower salary, which can often distort the true cost of a deal when speaking in the long term.
Carvalho has risen to become one of the Primeira Liga's most impressive midfield generals over the past year or so, but £24 million would still be a significant fee to part with for a player who's relatively untested among the European elite.
ESPN FC's James McNicholas has backed the move, however, predicting that the 22-year-old can ease the shift of Mikel Arteta's gradual gravitation toward the Emirates Stadium exit, likening the Portuguese international to past Gunners great Patrick Vieira.
Carvalho made 29 league appearances for Sporting last season, picking up eight yellow cards in the process, an average of just under one every three games.
With the likes of Jack Wilshere and Aaron Ramsey around him, the burden of relieving pressure on his potential Arsenal defence could be lighter in the Premier League, but Carvalho could find the English top flight suited to his aggressive style.
It's largely believed that a tougher midfield presence is required at the Emirates, and even though no motions have been made as of yet, three weeks of the summer transfer window remain in which to tie up a deal.
