Manchester United midfielder Nemanja Matic expects a massive challenge for Serbia's World Cup clash with Switzerland. Following a win over Costa Rica in their opener, Serbia can clinch their knockout-round place by beating the Swiss tonight. "Of course we are aware of the fact that if we win we will have progressed from the group and of course we will do our best for that to happen but you know we are facing a very good team," said Matic. "The Swiss team have a lot of quality and we respect them. "They have qualities throughout their squad, excellent individual players and team spirit. "We expect a hellish game but we are going to be ready for anything.".
