The England international is mot expected to be fit for first-team action again until next year after damaging his ankle, which has given Arsene Wenger a selection headache with Mikel Arteta and Abou Diaby also sidelined.
The Frenchman is understood to have been interested in the 22-year-old over the summer, but Sporting’s rumoured £37m asking price – the player’s release clause – was a possible stumbling block.
The Lisbon giants recently acquired Carvalho’s full rights from third party owners, and it’s believed that this was a move based on selling on the youngster.
A fee of a little under his guaranteed exit sum may be accepted, with Manchester United one of a host of other clubs chasing the man dubbed the ‘new Patrick Vieira’.
Although a key man at his current club and a Portugal international, Carvalho has hinted recently that he could leave Sporting:
“We all have ambitions and I hope one day to play in the best leagues in the world, the English or Spanish,
“It was not this year, but if I continue to do my job as I have done so, it will certainly come sooner or later.”
