Mata put Chelsea ahead
Chelsea marked their Club World Cup debut with a comfortable victory over Mexican side Monterrey to secure their place in Sunday's final.
Juan Mata put Rafael Benitez's side ahead in the 17th minute, sweeping home from inside the area.
Fernando Torres's deflected goal just after the break made it 2-0 before Monterrey's Darvin Chavez turned Mata's cross into his own net soon after.
Aldo De Nigris curled in a consolation for Monterrey in stoppage time.
However, while John Obi Mikel played the full match, his Nigerian international team mate, Victor Moses was a late substitute replacing Torres.
