Arsenal plan to upgrade Alexis Sanchez's contract.

The Sunday Mirror says Arsenal are ready to offer Alexis a five-year, £130,000-a-week new contract.

Chile international Sanchez - who helped the Gunners win the FA Cup last season and scored the winner for his country in the summer's Copa America final - has proved to be an outstanding buy for manager Arsene Wenger.

Forward Alexis cost £29.75 million when signed from Barcelona in July last year. And he has impressed everyone at the North London club - staff and players - with his attitude and his commitment.
