Inter Milan cruised to victory in their Club World Cup semifinal.
The Nerazzurri thrashed Seongnam 3-0 in the Club World Cup semi-final with goals from Dejan Stankovic, Javier Zanetti and Milito.
"It was not an easy game and we faced a very pacey opponent, but did well," said coach Rafa Benitez.
"Perhaps we were lacking a little sharpness, but we will improve. Diego is important for us and represents a great reference point in attack. We knew that with Milito we'd be more dangerous."
Julio Cesar, Milito and Cristian Chivu returned from injury for this tournament, but Sneijder picked up a muscular problem in the opening minute.
"We lost him straight away, but the team moved well anyway," added Benitez.
"I think he has a muscular strain and it's almost certain he won't be there for the Final."
