Switzerland, playing with 10 men for most of the second half, hung on to earn a 0-0 draw with Croatia on Sunday in an ill-tempered match littered with yellow cards.Croatia had most of the play but squandered several chances and also found themselves up against a goalkeeper in form in Joerg Stiel, at 36 the tournament’s oldest player. Seven players were shown yellow cards in this opening Group B game — four from Croatia and three from Switzerland.
