Argentina plays very well in the last minutes. Before that, they are simply careful and do passes. They also create dangerous moments here and there but goalkeepers always played very well against them but in last minutes they sense the fear of loss and go in full attack mode, they have an amazing, a warrior spirit and I like that but that can't always give them luck. They have to change something in their strategy or they won't be able to win against Switzerland and if they manage to win, Norway or England will be a huge trouble for them too, nothing to talk about Spain or France.
Switzerland played very well in latest World Cup and Euro, and they're truly more experienced than Egypt so they will start a match against Argentina with belief that they can do better than Egypt did. It possibly makes them stronger while with Argentina, after two dramatic matches against Cape Verde and Egypt, they actually learned some valuable lessons. They likely knew that there will be many opportunities to make comebacks when World Cup goes to last matches and opponents are stronger than previous rounds.
England want to bring football back home but they will have to beat Norway in a quarter final match in next several hours. Since 1966 World Cup, England have never won any other big titles from World Cup to Euro and they currently have a very good player generation that can help them actually "bring football back home".
