Amorim and Man Utd board to clash over Casemiro

Off contract in June, Casemiro's deal carries a 12-month option.

And given his form and leadership, Amorim is eager to see the Brazilian veteran to extend his stay another year.

However, TNT Brasil says triggering the option won't be a routine task.

United management want Casemiro to accept a pay-cut for the new 12 month arrangement, a request he is expected to reject given the offers he has from the Middle East.
