Premier League big boys Arsenal, Manchester United and Chelsea will face a major battle with Barcelona and Real Madrid if they are to land a star emerging at Sporting Lisbon.
William Carvalho has been a sensation so far this season and his performances have drawn comparisons with a Gunners legend, with him being dubbed as the 'new Patrick Vieira'.
With such a tag it is little surprise that Arsene Wenger is prepared to battle his rivals Jose Mourinho and David Moyes, but now Mundo Deportivo are claiming that there is interest out of Camp Nou and the Santiago Bernabeu.
The report claims Barcelona and Real Madrid are ready to go to war with Arsenal, Chelsea and Manchester United, and claims a deal for the 21-year-old will cost in the region of €45million.
Carvalho has been outstanding this season for Sporting and has won the Player of the Month or Young Players of the Month award in the Primeira Liga on three consecutive occasions.
He is a physical defensive midfielder and the report claims both Carlo Ancelotti at Real Madrid and his counterpart at Barcelona, Tata Martino, see him as the ideal addition to the base of their respective midfields.
All three of Arsenal, Chelsea and Manchester United require some long-term planning for that area as all have players over 30 currently occupying those berths.
However, Mourinho may not be as keen as Moyes and Wenger when it comes to his compatriot, as reports are suggesting a £21million deal is imminent for Benfica midfielder Nemanja Matic, who only left Stamford Bridge in 2011 as part of the deal to sign David Luiz.
