Manchester United defender John O'Shea has dubbed new teammate Javier Hernandez the 'wildcard'.
Hernandez will join his United teammates when they fly to Mexico for their friendly with Chivas.
O'Shea told manutd.com: "He's going to be a wildcard for us.
"The World Cup brought him to the attention of a lot of people, but other league teams might not know his qualities. So that should help us. He looked very sharp and I think he'll cause lots of problems for defenders and score a few goals."
