The Argentine hopes for all three points at Old Trafford.
West Ham United take on Manchester United at Old Trafford today hoping to get back to their best form.
The Hammers started the season in brilliant form but have gone off the boil slightly in recent times.
Injuries to key players such as Dimitri Payet, Diafra Sakho and Enner Valencia have not helped but that means a chance for some of the other West Ham players to come through and take their opportunity.
The mercurial Argentine has now tweeted ahead of the game with Manchester United today, making it clear he feels the club can get back to winning ways.
Great match to do well and get back on track!!!— Mauro Zarate (@mau_zeta) December 5, 2015
