Alexis Sanchez's return to training with Arsenal has been cast into doubt due to the flu.

Sanchez is out of the country and his representatives have been in touch with the club.

Sanchez would like to leave Arsenal this summer to join Manchester City. Paris Saint-Germain is also interested in Sanchez though he would prefer a reunion with Pep Guardiola.

Arsenal has remained steadfast that Sanchez is not for sale.
