Robert Pires has admitted he is unsure whether Alexis Sanchez will sign a new contract at Arsenal.

The Frenchman, who is currently working alongside Sanchez as a coach, said he speaks with the striker every day - but is still none the wiser as to whether he will renew his deal with the club.

Alexis Sanchez's current contract runs out in 17 months time and the Chilean has yet to indicate whether he will renew his stay at the club beyond 2018.
