Arsenal‘s Alexis Sanchez beat his gloves to the ground in frustration after a last minute tie with Bournemouth. His emotions continued in the locker room where he did not speak to any teammates after the game.
This could be a sign of a departure from Arsenal, his contract is set to expire June 2018 and Inter have him on their list of transfer targets.

come to sit on our bench and see what frustaration is …
and he will be happy here?
Any fringe chance of signing him probably lies in reaching 3rd place this season. Very unlikely.
Also Perisic would have to be sold.
