Former captain Nasser Hussain has insisted that England will be the happier side after day one of The Ashes.
The hosts batted first in Cardiff and scored 343-7, with Joe Root reaching 137.
Australia made a bright start to the day and took three early wickets, and Hussain expects them to be disappointed with the score at the end of play.
He told Sky Sports News: "You'd feel England are the happier side. Australia will be sitting there thinking we had a missed opportunity today. On the first morning of The Ashes, they had England 43-3, and it could have been four down, with England's star player Root gone, but they put the chance down.
"The other thing that's very important is that [Mitchell] Johnson has gone wicketless. He was the main man for Australia, with 37 wickets last time round. He has not hit his straps yet and that mental scarring has not resurfaced on day one. The last thing England needed today was Johnson ripping through them again."
Moeen Ali and Stuart Broad will resume at the crease tomorrow morning.
