Orsic has hit the headlines recently having made himself a familiar foe to Hammers’ rivals Tottenham, following the 28-year-old’s sublime hat-trick last week to send the North Londoners out of the Europa League.
This season has been a coming of age campaign for Orsic, after indifferent spells in China, South Korea and his homeland previously.
In 38 outings this term, the winger has scored 19 goals and added eight assists – including five goals and two assists in the Europa League.
Although relatively blessed in wide options in the Lonon Stadium squad, with European competition looking likely next term, Moyes will need each and every one of his options.
Orsic’s versatility will be an additional plus and offer flexibility in selection.
