How Arsenal's Strongest line up will Look with William Carvalho

Arsenal desperately need quality players in this winter transfer window to go far in Cl and challenge for silverware.
However, more than any other signing, Gunners need to act fast and sign a top quality central defensive midfielder.
One strong DM who has been linked with a move to Emirates Stadium for quite some time is Portuguese and Sporting CP star William Carvalho.
The 22 year old star is rated amongst the likes of Khedira, Javi Martinez and has the potential to become World Class.
Carvalho can be the man to help solve Arsenal’s defensive concerns as the Gunners do actually have their CBs fit but lack of defensive support from midfield has been a worry with Arteta, Flamini out injured and past their best even when fit.
As per the provided Daily Mail link, the Primeira Liga star is eager to move to England and Arsenal should really waste more time in securing him before anyone else meets the asking price and steals him away.
Here is how Arsenal’s strongest line up will look with William Carvalho in the side.
